The belt arrived on time and exactly as described. I followed the directions and gave it a try. Initially, it was a bit uncomfortable—probably because I don’t work out much. One big reason I chose this model is that it doesn't require replacement pads, and that’s been a huge convenience and cost-saver. I use it regularly. I really appreciate the different modes and intensity options—it gives a lot of variety. The pulsating effect is strong and effective. Overall, I’m happy with the product and excited to see how things progress long term.

The belt arrived as expected. I followed the directions and tried it out. At first it was kind of painful because I don't exercise much. (I hate sit ups) I had to keep the intensity below 7. Now about six weeks later I wish there was a to go right to level 15 button because that is all I regularly use. Level 7 or 8 is quite relaxing, I can even fall asleep. I can't say about long term yet, but I now have to wear a belt or my pants keep dropping down when I walk. I selected this belt because it did not require the purchase of extra pads. So far it works great. I am wearing it right now, with a computer in my lap

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.

Very easy to use and works well. Holds a charge a long time and I like that it doesn't require disposable replaceable pads. Good variety of functions/pulses/strengths.

I've tried multiple ab stimulators before, but this one stands out as the absolute best! It delivers **exceptional results**, helping to strengthen and tone abdominal muscles with remarkable efficiency.What I love most is the **multiple intensity levels**, which provide flexibility to adjust based on personal comfort and fitness goals. Whether you're a beginner or looking for a serious challenge, this stimulator has you covered.Compared to others I've used in the past, this product **outshines them all** in terms of effectiveness and overall quality. If you're looking for a convenient, powerful way to enhance your core workouts, this is definitely the one to get!

I have had this 3 years almost and just love it. I use it after the shower and I can certainly tell a difference. If I go a week without using it and then come back to it, you can definitely feel the difference. With that said, I can only account for someone on the smaller side. I am already in shape and use this to fill in when I don’t have time to work out. You can’t expect to use this and get ripped if you are too heavy or it can’t engage with the ab muscles to begin with ….

This device definitely stimulates your muscles but my product kept shutting off shortly after I turn it on. I owned it less than a month and noticed that it was acting funny while carrying a full charge. Personally, it was OK.I did not use this device for weight loss/toning purposes (and if you believe that it does then you’ve been fooled, only a calorie deficit will do that). I used this device to help with my sore muscles after my intense workouts.

***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.
