MarCoolTrip MZ ABS Stimulator,Ab Machine,Abdominal Toning Belt Workout Portable Ab Stimulator Home Office Fitness Workout Equipment for Abdomen Black

This is a good product. I wasn’t sure if this belt would do anything because it’s my first time trying a product like this. I do think the belt is working though. My stomach does feel a little harder and more toned than before I started using the belt.I can’t say it’ll give you 6-pack abs without exercising. That would be impossible! But it’s a useful tool to help you get more fit. The Velcro is strong and durable. You attach an electronic simulator pad to the belt with two small buttons. The buttons are not strong and the pad falls off if you jostle it too much. But I won’t lower the rating since the belt works just fine as long as you sit still while it’s working

I’m very impressed with this muscle stimulator belt I have recommended it to several of my friends. I’ve purchased others and returned them because this one is much much better. I like to wear it several times a week and I feel like it is making a difference in my abs. It’s very easy to use and I can honestly say that my abs are looking better.

Works fairly well compared to other brands. This one actually has a band to secure it to your abs and not just the gell patches to stick to you. However, it does wear out and start not working unless you hold it against you. But that took almost a year of use before that happened. Over all, it's a pretty good one to get.

The device was helpful in weight loss.I used it while walking and you can really feel the muscles contracting. The device helps optimize time by helping stimulate muscle while doing light exercise.So far I have lost 10 lbs and hoping to lose more.

I was skeptical about this product, but it truly has made a difference. I've had three children and although I work out daily I was looking for a quick way to achieve more abdominal definition without adding gym time. Adding this along with refocusing on protein intake was a game changer for my progress.I wear the belt while getting my kids ready for school. It's intense but not unbearable. The different modes and intensities are great for targeting different areas. It's lightweight, sticks well and the removable charging feature is great. It holds a charge well and overall the device seems durable.I definitely feel stronger in my core and see better definition.I would recommend for busy moms who want to supplement their workouts in an easy way.

My wife purchased this to use at home while doing other workouts and while working from home. The belt fits great and you can really feel the product working! Its incredibly easy to use and doesn't take very long to charge. What's even better is the charger is USB-C so almost any phone cable now adays will work. If you need something to use at home while getting things done around the house while also wanting to tone up the abs, this is a great way to go!

It definitely does work to contract the abdominal muscles, but I discontinued use when I started randomly feeling like I was getting zapped by it when I wasn't wearing it. Maybe I was over-doing it, but I didn't care for that after-effect sensation.

***5-MONTH OWNER UPDATE***I highly, highly advise you to not buy this item. Please read all the negative reviews and take them seriously, they all note that this thing isn't durable and now I see that they were all correct. Do not buy this item unless you're fine with replacing it a few times a year.I have owned this thing for about 5 months, and while I had positive things to say about it at first (which you can read in my original review below), I am extremely frustrated because its performance has totally and suddenly degraded, to the point where it is no longer really usable at all.I use(d) this belt twice a day for 4-5 days a week, making sure to wipe off sweat and charge it at least once a week. Everything was fine, until about a week ago. Suddenly the strength of the vibrations became significantly weaker. I was on the 6th mode at 15 strength for a while, and I grew very familiar with how it felt. Now the 15 strength feels like how 5 strength used to feel, and anything under 10 strength barely tickles. The plastic piece just lost all of its power seemingly overnight with no change in routine or anything. To be clear this isn't related to my own growing tolerance or anything, the first 10 strength settings barely vibrate at all anymore, and it was not like this just a day earlier.What's even more frustrating is that the company that sells this item does not respond back to messages. I had to contact Amazon to be able to message them in the first place, there's no trace of them online and they don't make their contact info readily available. Not even an email address or a Facebook page. And of course, after several days they still haven't answered my message, I was trying to find out if this is covered by any kind of warranty. It was a $70 item, I'm genuinely so frustrated with all of this.The only reason I'm still giving this item two stars instead of one, is because I really did like it when it worked. It provided solid resistance to my abs and I grew to appreciate the routine of using it. But now it's barely functional and the seller doesn't bother to respond to messages. I don't think $70 is a fair price for an item that will only last a few months, and I'm really disappointed with this overall.***ORIGINAL REVIEW***Okay so I've been using this thing for a few weeks now and so far I like it. Obviously this isn't going to actually give you a six-pack but I have a noticed a very, VERY slight bit of tone in my abs - though I'm using this while also eating relatively healthy and exercising five days a week. This thing, on its own, will not produce significant results. But I like it as a supplement to my usual fitness routine, simply because I hate doing abdominal exercises and this does do a good job of mimicking the feel of crunches.I wear it twice a day, five days a week for 20 minutes each "session". That's exactly how much I can handle before the pain becomes genuinely difficult to bear. I'm currently on level 10, mainly using the sixth mode. There are six modes and each mode goes from level 1-15. I had to start at level 4 and have been working my way up every couple days. Even though I can handle level 10 on my preferred mode, I can't handle level 10 on any of the others - so each mode definitely provides a different feel, which I like.So I can recommend this thing, as long as you keep your expectations in check and understand that it isn't a miracle device. However I'm mostly writing this review because it has a couple of major problems that I want to address:First of all, not a huge deal, but I cannot get a read on the battery life for this thing. One time I had to charge it after a week of use, then after a day, then after a few days, despite my sessions all being the same length. When you charge it, it has a little red LED light, and when it's fully charged that light disappears. I wish it could alert you when you have a low battery, maybe by flashing red a few times when you turn it on. That would be helpful.My main issue however, is the fact that this thing doesn't have a kill switch. There are three buttons: the plus/minus buttons to increase or decrease your intensity level, and the M button to switch between modes. The difference between one level and the next feels massive. I was on level 8 for a few days, and thought I was ready to switch to 9. But I was wrong - level 9 immediately gave me a bad cramp that I couldn't handle. But because there's no kill switch, I had to rapidly click the minus button 10 times to turn the machine off, while wincing in pain the entire time. There needs to be an off button for this thing! It actually makes me a little anxious to increase beyond level 10. It was a massive cramp, like somebody kicked me in the side with all their strength. Genuinely cannot understand how they could overlook such an important feature like that.But that's only enough to reduce my rating by a single star, because overall this thing is still very good. It fits comfortably, it provides a solid "workout", it's easy to clean/store, features a decent amount of options, etc. And most importantly, it does seem to provide *some* difference, as I haven't changed my workout/diet while using this thing at all, yet I've observed a (very slight) change. And after only 3 weeks of use, I really can't complain about that!EDIT: I've been using this thing consistently for a few months and it definitely feels durable. I also noticed that the battery is pretty good actually, I charge it once a week which seems fine so far. Not as inconsistent as I originally thought.In regards to the lack of a kill switch I've found a bit of a workaround: when you switch between any of the six modes, the intensity level automatically goes all the way down to level one. I'm on level 15 at this point (only with the one mode I consistently use), and I no longer develop cramps at any intensity level. But if you DO need to quickly turn the machine off, simply click the M button once, and then click the minus button once. It's a bit clunky and I really do wish that it just had an actual off button, so I'm keeping this review at four stars. But it is at least better than what I was doing before (clicking the minus button rapidly to turn the machine off).Overall I've grown more positive about this machine over time, I definitely think it's worth getting if you use it consistently. Also I forgot to mention this in my original review but it charges via micro-USB which sucks, for the price it really should be using USB-C.
