MarCoolTrip MZ ABS Stimulator Reviews: Scam or Legit?

I got this after trying the gel pad “booty” ems machine. This one is soooo much better than those things. Just spray water on the pads and it gives STRONG contractions. I wrap the stomach belt around my booty and it works way better than the other did. Im actually sore after using it and I am already in good shape and work out regularly. I wear it while doing things around the house for the extra and still work out. I see visible improvement with cellulite and muscle tone. Ive been using it for about 5 weeks. I got one for my husband and my uncle. Both love theirs too.

worth the purchase i have only had this product for three days using about twenty to thirty minutes a day i love it! and so does my fiancé!

Works well. I like that it does not have the pads that need replacing. Only problem is that I have a 30 inch waist and this belt is way to big to fit me correctly, I had to modify it to make it work.

I got MarCoolTrip MZ ABS Stimulator because I was looking for something that didn’t need the gel Pads, So Far I am really enjoying the product only have had it for a few day so hopefully I’ll see some results….

Overall I like the MarCoolTrip MZ ABS Stimulator and it definitely stimulates your muscles. However, the arm bands were a bit intense for me, even at tje lowest setting. My arms don’t have much fat so I guess that’s why it was so noticeable. My problem area is my abdomen, and it was not uncomfortable using it there. I do recommend.

Didn’t know what to expect when buying. It was a little odd but not too bad. I know it’s not a magic product to make me lose weight, but time will tell if it lives up to fatt burn or muscle sculpting, haha.

Doesn’t really work as it says it’s supposed to and hard to adjust on one’s self.

I’m one inch less than the recommended inches and the Velcro will not stay. I need to buy an extender. On mode two, I could feel a slight flutter but it didn’t feel like it was actually contracting the muscle

I noticed that these die very fast. Its not comfterbal and not great fitting and the other thing it dont come with instructions.

I’ve bought other belts like this where you have to apply gel and the nodes have a pad that easily deteriorate over time but this is quick simple and just needs water. Pretty cool

So I really bought this item for the arm cuffs. The fact that it came with the abb belt was a bonus as I already have one from another manufacterer.The cuffs are awesome, they work great.The abb belt is absolute rubbish. Only works on one abb, so lame. I returned it and got another one, same thing, total junk.So, if you want the cuffs and are willing to pay $30 for them (worth it) go for it. If you are looking for a good abb stimulator, DEFINITElY go somewhere else.

Don’t bother buying this. Doesn’t work, battery life is terrible, and don’t feel anything.

Felt good at first then started hurts don’t recommend

I don’t know how to make MarCoolTrip MZ ABS Stimulator work. I charged it but it didn’t cut on.

 I suggest using a conductive gel instead of the water. I feel the power of the belt a lot more with the gel. I haven’t been consistent so I don’t have results yet but after I finish a session each time I definitely feel like I just left the gym. I’m only up to level 3 but they do have more intense levels.

Did not come with a charging cable at all, so trying to find the correct one so…that is always fun !!

Quality material. This product is therapeutic for the muscles rather than toning them. I’m excited to follow it with discipline. I’m happy to reduce the size of my belly and in less than a week I’ve noticed a reduction in my belly.

Doesnt even turn on. Doesn’t come with directions. Very uncomfortable. Would not recommend.

Not very sticky and barley worked don’t feel a change

Not what I expected, jus to flimsy doesn’t work as good.

Was very easy to use and charge the 3 rechargeable disks for abs and arms. I definitely didn’t like how the item shocked you. I would not but this again

I could definitely feel this working! It kinda feels like a tens unit but it on muscles I’ve never used a tens unit on. According to the instructions, you are supposed to tense those muscles as if doing a sit-up or whatever (depending on the muscle group you’re focusing on I do feel my core is a bit stronger after using this for 2 months. I still have a bit of weight to lose before results are seen.

MarCoolTrip MZ ABS Stimulator is definitely not made for heavier people. Barely fits around me. Came with no directions . And everytime I put it on and walk around it un fastens due to it being smaller then needed. Dies quickly.

MarCoolTrip MZ ABS Stimulator is a good product but designed for a larger person. If you are a person with smaller arms or waists they are WAY TOO BIG

I purchased this abs stimulator a few months ago, but I frequently use it during my workout routine. It packs a huge punch and I have seen a difference in my abs. It’s a great tool for anyone to use in addition to their workout regime.

Bought this in April and it worked for almost 6 months to the day and then the main piece that you attach to the belt just completely stopped working altogether

Don’t expect to look like the advertisements in the picture. But, it does work. I’ve only gone to level 6 and it goes much higherWould buy again!

I need to be more consistent with this to get adjusted results I feel like but it does stimulate your abs. Instructions not detailed and helpful so that would be nice

I waited for a while before writing this review. This is of great quality and has been working well since I purchased it. I would recommend.

I am very happy with this product. I use it during my workouts in the gym and at home. The pulse strengths are adjustable as well as the mode options and I get an awesome workout on my abs. I would definitely recommend this product.

Great buy! Works well and fast! Great value for your money! Will be buying this again as a gift!

This device really works!! It definitely exercises your abdominal area without you doing a thing! I wouldn’t recommend on anyone who may have a stomach hernia as it is powerful and may cause pain

This MarCoolTrip MZ ABS Stimulator must was made for extremely skinny men and woman. The ab belt and arm bands are extremely small and can’t be wrapped around my waist or arms. Will be returning.

I supplement my core work with this device a few times a week just for added toning. Seems to work well!

Nice, feel muscle pain next day, means it works. Comfortable, made of neoprene and makes me sweat, which is good as well. Using when running and driving.

Great quality! I bought a second one for my wife, highly recommended!

I use it for a while but didn’t get expected result

Comfortable to wear while working, either standing or sitting. Convenient 20min timer.The two smaller wraps won’t close around my biceps, but work for forearm pretty well. Super inexpensive way to have some maintenance between workouts.

I like it because it was easy apply and I did not the smell

Comfortable. Easy to use. Don’t worry about batteries, just recharge it with the USB cable.

Just received a few days ago and immediately had to use. I absolutely love everything about these belts. No gel patches just spray and wrap. Very impressed

Appropriately stimulated and trained.I believe that continued use of this product will help my abs. It is easy to continue because there is no need to use a gel pad, and there is no need for the hassle and cost of replacing it.

It’s very well made and you feel it work right way.

I’m a total skeptic, but I’ve always wanted to give some of these ab stimulators a try. This generation doesn’t use the sticky gel pads, instead you just spray some misted water onto the belt pads right before you put it on to make a good electric contact. It’s super fast and easy.Now, if you’re overweight this isn’t going to make your abs visible overnight all by itself or anything… but I’m in my 40’s, and semi-fit with just a thin layer of fat (dad bod) that I can never quite seem to keep off. I’ve been using this multiple times a day for the past week or so, and my wife literally said – ‘I can see your abs again now!’ I’m not sure who is happier about this, her or I, but I plan to continue using these for a while! I do find that it works best if you use it multiple times a day. I actually double up my sessions, so I use it for 40 minutes at a time while I’m watching tv or playing video games… or sometimes even while I work at my desk.

Good for strengthening and toning but you have to give some time to see it’s effectiveness. A little weak on one side so I alrernate by placing it with control unit upside down every other session.

I have bought this product twice and both lasted 3 months, when it works it’s great but I’m looking for a product that works and lasts!

It was working fine and then wouldn’t charge anymore after 1 month.

I have wasted my money a few times on these abs devices. I got super tired of 2 things. 1. Not powerful enough. 2. Sticky pads don’t work after 4-5 times of use. I bought this and holy moly! It’s perfect. Seem like it will last a very long time and guess what? First 2 days on level 4-5. 3 day #1-2 was why enough. It goes to 9, I believe. My stomach was that soar. I see results after a week! Crazy good. I think I’ll buy a second for back up and maybe more for present to some buddy’s. Thanks

I held off on reviewing this long enough to see if it actually worked (I was definitely skeptical). It turns out that it does. With regular use (one hour a day, every other day) it will tighten and tone, as well as strengthen your ab muscles (as proven by attempting to do sit-ups periodically throughout the time I’ve owned this). The problems are many, however. First, the electrical portion of this attaches to the belt with some small snap-button style snaps that barely hold it on. Second, the instructions are terrible. Based on the pictures, this belt has nine settings, but there’s nowhere that actually tells you what the settings are. Third, it drops the connection with the App consistently. It’s a struggle getting this belt to the point where it stays connected and starts to work. I’ve found I can get it to consistently disconnect by simply changing the duration from the default 20 minutes to anything else. Fourth, if you’re thinking you’ll just use it without the app… good luck. There’s no way to tell what you’re doing without the app. The electronics portion of the belt is just a few buttons with no indication of what you’re actually selecting.

I’ve been using this for about 3 months now and I’ve been very impressed with this. I’ve used other TENS and MENS devices before and this is by far the most comfortable one I’ve used. It’s easy to clean and the module is removable to help with cleaning and charging. My only complaint is I wished this used USB-C instead of micro USB but it’s not the end of the world.

I was ready to return after read limited instructions on how to use but a list of safety reason why most people should not use especially not to use in a bathroom to avoid electric shock due to humidity. However the instructions stated to spray water on pads???? So I read the 707 reviews and decided to try. After one use, it is amazing and I cannot imagine that I will not benefit. I will return after a couple of months to update. My only concern at this point is no mfg contact info and if it last. Eventhough there are no real instructions on mode, you just have to play with it to get your setting and know how to turn down if too intense.

Belt works excellent when used with cream to burn even more belly fat

The unit is powerful. Even on the first setting. I’ve noticed that one side is much stronger than the other. To compensate I flip the detachable unit over between sets.

Purchased and it does indeed contract your muscles

I bought one of these when they first came out and they were pretty expensive. I really didn’t like it so I returned it. Years later I bought another one that was very simplistic and I used it almost every night. I really liked how the stimulation worked. I don’t know if it really works, but I liked the way it worked on me.I don’t know if I’m going to get strong abs or any part of the body like that but the way that it stimulates the muscle, does something to you the next day. I mainly use this because I think it feels good and it’s good for my well-being. Whether it actually works on my abs I don’t know and have never seen any drastic changes in my life.It does take a little time to get everything working and understand how it works.So don’t expect to look like a muscle person unless you work those abs in the way that other professionals do. But again, the stimulation feels really good.

I used it for several weeks, a couple of times a week. It actually build and toned my abdominal muscles. I would not believe it except the muscles were sore the following day. It works as it should.

Love the different settings. Really enjoyed it making my muscles flex and tightening. I think time will show good results. It’s not a quick fix kind of deal but if u do it consistently for a long time you will see results.

AB wheel roller works very well. After losing weight it was time to start getting more definition and work on my core. This device works amazingly well and puts an amazing amount of focus in the right places.Thank you

I like that this Ab belt is easy to wear and adjust. While I don’t think it will give you a 6-pack stomach, it will stimulate and exercise your stomach muscles. Maybe if you are super tone to begin with, I can see it helping to maintain. It will work great for stimulating over worked muscles. It has very good intensity and plenty of levels so you can reach the desired amount of stimulation. It is easy to use and control without fear of raising it up too much. The Velcro stays attached and grips well.

Works like a charm not only for ab stimulation, but I have also used it on my neck and back to relieve stress/tension in those areas!

Me gustó mucho vomo trabaja solo que constantemente se cae el aparato quelo activa

This abdominal trainer is much easier to use than those which use gel pads. The belt gives more tension and it will not wear out like the gel pad attachments

Great with contracting abdominal muscles and the has a built in timer per session. But, be careful with making sure there’s enough water sprayed on inner pads and maybe add any kind of gel/Vaseline you may have laying around to skin prior to using ab stimulator. This is to ensure you don’t have tiny burns, which will happen if there’s not enough moisture between pads and skin.

I have second degree burns to my stomach! Be careful! This is a dangerous

Fascinating device…I have toyed around with Tens machines in the past because of old Bruce Lee vidoes where you would see him hooked up to all these diodes and electrical muscular stimulators. If my boy Bruce Lee endorsed it then forevermore in my mind it was an option to get Bruce Lee asthetic.Well this isn’t going to make you look like Bruce Lee or get those muscles, but it will actually give you a workout and maintain whatever you have as far as I can tell. I don’t see myself making much muscular gains on my ab area doing these, but I do feel like I can maintain my current physique and maybe get some cardio as well.Its not very complicated…you just spray a couple of dabs of water on the belt that is going to touch your belly and strap it on. Turn on the main button then go into the app. You can change the settings for your particular setup and away it will go. I started out around level 5 for 10 minutes working my way up to 11+ for about an hour. Its very convenient to use while I’m on my computer doing some work.9/10 I would recommend it or at least the principal of it. I hope this review is helpful.

Easy to use, comfortable, great value and works while I do other things. I love it and you will too!

You can feel that works even on the lowest levels of intensity 👍🏼

I purchased this stimulator mainly for my back by switching it to my back. The key is to use water or it doesn’t work. I spray water directly to my back and the pads on the belt. I’ve ordered TENS gel to experiment with that. Highly recommend!

Really loved using this abs stimulator! Highly recommended!!!

Sometimes I like and sometimes my packages are placed in plane sight

I like it that you do not need cream or any other liquid to put on your tummy. We think it’s working but maybe slowly

Ive been using almost daily for about 2 weeks and was feeling like it was making a diff. The day before yesterday, I noticed a wound. Yesterday i found another spot on the other side of my stomach but smaller. They both appear to have a burn spot in the center. They dont hurt but not willing to risk more burn spots or aggravating these two worse. Too late to return. Trash time. I so wanted this to work out:(

I love this an belt. It’s been the best that i have bought this far. I’ve purchased other belts in the past but they don’t last.

I used this product while driving 10+hrs a day. When I get drowsy it intensely stimulates me keeping me up giving an intense workout,

don’t expect a miracle. it just helps to load the abs muscles a little bit more after the gym. good quality. easy to use.

I like the multiple speeds of the belt. It has been working great. 5 Stars

I liked how this product was effective and easy to use. Using it regularly is what I think truly helps get results.

Haven’t used it long/consistently enough to see a visible difference but am hopeful that once I do I will notice it helping.

 I’ve been using the Abs Stimulator for over a month now and can definitely see results. I wish I had before and after pics. I put it on almost every day and keep it on for about 20 mins. It works with consistency

I use it every day. I have had multiple surgery’s on my abdomen and now conventional sit-ups are not an option for me. This device has greatly improved and flattened my abdominal muscles!

Once you put on the belt and turn on the ab stimulator, your viewpoint will change. The vibrations flow right through the belt into your midsection instantly. The pressures feels like tiny rapid punches through the gut. Increasing the intensity increases the workout. The belt contains different modes for different ab pressure rhythms. It’s very convenient to have. I highly recommend it.

Strong settings, multiple modes. Works well with diet and exercise.

I really enjoyed wearing this product it wasn’t form fitting. You can actually feel it working on your stomach. This does work. I’ve had it about a month. I could only do a few situps before, then. Now I can do a lot, if I choose to. My core is stronger, just by using this device.

I love the product. Have been using it for a couple months and I feel that it has tone my ads.Great product and service

I can go anywhere and where it under my clothes I can do pretty much anything in it that I normally do

Very very good have seen alot changesI suggested you give it a try

This is an amazing tool to stimulate your abs while working out.

This stimulator does work. I feel a difference while using and a few hours after. All in all a great product

I got the MarCoolTrip MZ ABS Stimulator to use to build my abs while doing other activities, watching TV, reading or working around the house and it is causing my abs to contract and they as if I have been doing an ab workout.

It takes some time to get used to. I found the feeling very uncomfortable at first. My wife likes it and is more frequent user, I think it works, it’s a localized tens machine for your abs. Time will tell.

I use this MarCoolTrip MZ ABS Stimulator daily, and it has a strong effect on the production of abdominal muscles. It is very useful. I advise everyone to buy it

Funciona perfecto para mis abdominales y para hacer ejercicio. Todos los días la uso al momento de hacer ejercicio y si me ha tonificado mi abdomen inclusive he adelgazado mi cintura con esta faja

I havevused this daily for 2 months and have lost 2 inches around my waist!!

It’s a really good aid for losing belly fat and strengthening abs.

Strengthen abs. My husband loves it Like the various modes

MarCoolTrip MZ ABS Stimulator was easy to use – At first the lowest setting seemed hard, but after a few days I quickly got use to the feeling and advanced to the higher settings. I felt better after a week. It is a gradual, but noticeable abdominal muscle builder.

I used ab stimulator on my stomach and I can see the results already

I don’t use it constantly but it seems ok. You have to make sure you spray water on it before use. Otherwise, I enjoy using it.

very easy to use and efficient when having a desk job and not enough time for your daily workouts

I was a bit skeptical about the ab simulator when I first bought it. So far after months of use it has held up and the product works as described. The different mode options for along with level of intensity help with the different options of what works best for an individual. Worth the buy for anyone looking for extra core strengthening.

Es perfecto para hacer ejercicio involuntariamente

I have been using this stimulator for a couple of months now and I not only feel the difference, but I see the difference it has made a great impact on my well-being. Thank you abs stimulator for allowing me to feel better.

It’s easy to use and you don’t need any batteries.

It’s very comforting to have on while working out. Doesn’t get in my way while running. Definitely recommend

It’s okay. I can definitely feel the muscles being shocked. It’s not as sturdy as I had hoped. Seems like a cheaper, nylon plastic material.

Hubby uses MarCoolTrip MZ ABS Stimulator everyday since we got it. I can literally see it working on him. As for me I don’t love it on me. It didnt register me as a body on my back, then I didn’t like it for my abs. It’s like a centered tens unit. I do think its cool to be able to control this device from the app. The battery life lasts a few hours. After two weeks it glitched where it didnt charge for a day and then it did charge and immediately dropped to 80% battery life (according to the app) so that was weird. I think the price is a bit too much.

It took me a minute to get the power button to snap onto the belt. The belt has a couple of conduction pads built into it. It also has an extender and a spray bottle. At first I thought I was using it wrong because I didn’t feel anything, but then I placed my finger on the conduction pad and got zapped, so I knew it was working. If you don’t have it on tight enough, it will feel more like micro shocks. The higher the intensity, the more you feel it. It reminds me of a tens unit. With that being said, over time, it does have the potential to increase muscle tone in the area it is placed. The instructions are in small print, making it a little difficult to read, but I was able to get through the instructions fine. I didn’t download the app and was able to use it just fine without it. I do believe this will work its magic over time.

The ab belt offers a range of intensity levels, with 25 levels to choose from. This customization allows me to gradually increase the intensity as my fitness level improves, ensuring progressive muscle development. The ability to fine tune the intensity levels is a significant advantage, as it caters to individual preferences and comfort levels. The belt is adjustable and fits securely around the waist, providing a snug and comfortable fit during workouts. The breathable fabric ensures proper ventilation, preventing discomfort or irritation, even during longer exercise sessions. The lightweight design adds to the overall comfort, allowing me to wear it for extended periods without any inconvenience.

MarCoolTrip MZ ABS Stimulator is unlike anything else I’ve ever used! I was skeptical about it at first, but it can’t hurt me so I figure I have nothing to lose.Upon opening the box, there is a circular device with a power button and a + and – to adjust the intensity. This is the part of the device you charge, and it attaches to the belt. The “shark belt” is a soft fabric belt with a swole shark on one side and black silicone pads on the other side. These pads are where the magic happens! There is also an empty spray bottle for water, a belt extender to fit larger bodies, an instruction manual, and a USB charging cable (no wall outlet).The device is quite easy to use! I attached the circular piece to the belt, misted water on the black silicone pads and my upper abs where I placed the belt, wrapped the belt onto my body and secured rhe velcro, and turned rhe device on. I didn’t notice anything from the initial setting, so I turned it up a few levels. I didn’t feel comfortable downloading the app on my phone, so I’m not sure what level I used as there is no display screen and only a light that blinks blue when turned on and is solid red when charging.The sensation is very bizarre! Not painful or uncomfortable, just unusual. It feels like my abs are quickly being shaken back and forth. I do feel my muscles engaging, so I feel that this device really does work as described. It is not a constant sensation, it comes in waves. A few seconds of intensity and a few seconds to relax.The device has an automatic 20 minute auto off function. I did 20 minutes of upper abs and 20 minutes of lower abs while I laid on my bed. I’m curious about using this on other areas of my body, but I haven’t researched or tried that quite yet.I did just start using this device and the instructions say results can be seen in 4-6 weeks, so I’ll update my review if/when I notice a change. I started a few clicks above the level it is when it turns on, but I’ll increase the intensity as I get used to it.All in all, I think this is a really cool device and I’m glad I found it! I would gladly order again.

I’ve only used this a few days so the jury is still out – it’s takes a while to see realize the effects but I will update as I go.

This belt came packaged well.It is made out of good quality materials and the design is cool but that what the 2 stars are for.The app leaves much to be desired.The belt itself doesn’t really do much. It feels like vibrations.. or slight pinches, not painfull at all.I used this on all the settings included the highest ,I even wore this during exercise to see if it would add a little something extra,and I never felt like my muscles were contracted by the belt or getting any type of stimulation. It never made my muscles sore the next day like I had an extra workout. Maybe I have to much surface fat but I didn’t feel like the pulses even got past my fat layer to affect anything. Also I tryed to put this on as tight as I could and the top always stuck up away from my skin..

I expected to be able to press the power button and increase the intensity and use it but no. So I put it off for days. I hate having to download more apps. But to leave an honest review I had to. There are several settings that do vary a bit in the pattern and frequency of the little zaps you feel but every time you change to a different mode it drops the intensity to 0 and you have to bump it up again. I use somewhere between a 16-19 setting but it can go a little higher. It defaults to 20 minute sessions which works well for me too. I can’t sit still any longer than that anyway.It’s a fun sensation. When I put it on my abs, I could feel it engage the muscles. Not sure that it’s actually building muscle while I lay on the couch with it but it feels nice. It actually felt so nice, I later zapped the back of my thighs. Then I came back later for another break and sat down on it to zap my butt too. It reminded me of my years in physical therapy trying to build the muscles around my back during gymnastic training so I used it on my back too. The only thing that got to be a little annoying was that the receiver disc that snaps on to the best kept coming loose and when the electrodes don’t make a good connection it turns off and you have to restart.

My abs felt nice after use. The shark belt has three modes on the app. The three modes are mass, TENS and EMS. I could not figure out what the mass mode was. The mass mode shows to be slimming, but I don’t know what type of current it is.TENS is primarily used for pain relief.EMS is primarily used for muscle strengthening, toning, and rehabilitation.Without using the app, I would find it hard to know what I have it programmed on. This device is a lot more user-friendly with the app.I personally used EMS. I work out pretty regularly and started on that level 7. I use the device for 30 minutes. My abs felt nice after use but I could probably go up a level or two, but wanted to be cautious since I have not used this device before.I plan to continue using this device for the recommended 4 to 6 weeks. I did spray both pads with water. You must be wearing the device in order to successfully connect to the app. I like that you can see the modes. You can also slide to set the timer and choose the intensity level.I recommend this device if you’re going to use the app, I tried using the device without the app and I didn’t find it as user-friendly.

The MarCoolTrip MZ ABS Stimulator is an innovative muscle toning device that helps you strengthen and tone your abdominal muscles.

You wear the belt around your abdomen and connect it to the app on your smartphone. The app provides step-by-step instructions and allows you to track your progress and monitor your workout sessions.The EMS technology used in this ab belt sends electrical impulses to your muscles, causing them to contract and relax, mimicking the natural muscle contractions that occur during exercise. This stimulation helps to strengthen and tone your abdominal muscles over time.The MarCoolTrip MZ ABS Stimulator is suitable for both men and women and can be used at home, in the gym, or even in the office. It offers a convenient way to incorporate abdominal muscle toning into your daily routine without the need for dedicated exercise time.It’s important to note that while the MarCoolTrip MZ ABS Stimulator can be a useful tool for muscle toning, it should not be used as a substitute for regular exercise and a healthy lifestyle.

I have had this for a few days now and it is not easy to get started. Took about 5 minutes to get it on this morning. Instructions are as easy as pushing a button one time. If you turn it on and press the power button to “activate”, I discovered you must turn the power “up” using the + button several times before you can even feel anything happening. I mistook this for it not working.The product does initiate strong muscle tightening in the stomach. I believe it will do what it says over time.A couple of things to be aware of. The app (not required) has a very long and tiny font disclaimer. I zoomed in to read just a couple sections and it says up front all information collected by the app is stored initially in China, but may be shared across the world. I chose to not install the app, as it would directly link to my checking, security and so forth.Without the app, it will still work. Downside is there are no guidelines on how to use it, for how long, the intensity. I have it on a higher intensity and can already feel sore as if I had been doing a lot of sit-ups, and that is only 10 minutes in. I have no clue the recommended use, or any dangers for extended use.This is a use at your own risk, or if using the app (I hope that the app has guidelines).Side note, I am 5’9 and 205 lbs. The belt is only 40″ wide (with 14″ extension that velcroes onto one end). I managed to get the belt on without the extension, as it does stretch a little bit.

This thing really knows how to pulsate your abdomen. Super satisfied with the overall construction and the power. This worked great!

 So far everything you need is in the box. Seems to fit a little small and it’s not adjustable but there is an extender band that comes with it.
