SHENGMI EMS Muscle Stimulator,Abs Trainer Abdominal Belt with LCD Display & USB Rechargeable,Ab Belt Toning Gym Workout

I wasn't expecting that much given the price of this trainer, but it's still managed to be rather disappointing. The gel pads have serious trouble staying attached to the skin, even when brand new, so they tend to work loose after a minute or two as the muscles contract. There's also no practical way to clean them, and this device simply isn't good enough to be worth spending money on replacement gel pads all the time.The set consists of an ab trainer with eight pads, and two other trainers with only two pads each. There are also three interchangeable controllers, which have to be charged from a USB port. There is a manual supplied with the kit, which is one of the worst translations I've ever seen. It may have some unintentional comedy value, but if you're trying to figure out how to use it or troubleshoot the device's many problems it isn't very helpful. For example when trying to troubleshoot the poor gel pad adhesion, the manual's best offering is "ge pad pad (drying preventing pads, must be pasted Board holds sticky". Most of the rest of the instructions are similarly unintelligible. While we are on this subject, I can't help noticing some of the most positive reviews of this product feature a similarly unique approach to the English language.Just to address a point in the product description and some of the rather similar reviews. This device is not something that can be "worn unobtrusively under clothes" while working or doing other things. It has bright flashing LEDs on the front of it when operating, and tends to fall off if you try moving around. On the rare occasions it is sufficiently well attached to actually stimulate the muscles properly, the twitching makes it more or less impossible to do anything more than watch TV while it's active anyway.I'm not sure if this trainer actually makes much difference in terms of fat-burning, muscle toning etc. Not much noticeable effect after a couple of weeks. At current rate I reckon the gel pads will deteriorate to uselessness in another week or so. Unless there's a fairly spectacular change in that time I doubt I'll bother replacing them.

These are great! Had a brain wave and I put the abdominal pad on my neck when I had a migraine (desperation) it wrapped around my neck and the top of my shoulders, I put it on shoulder, setting 2, let it crack on. The stress in my neck was gone, migraine eased, I no longer worry when ‘that feeling’ starts. On top of which, the unit works fantastic for shoulders, abs, back, thighs, calves, there are three units and each has six programmes for upper arms, forearm, back, abs, shoulder and waist. Each programme has nine power settings.After heavy use, or if the adhesive pads dry out, wipe them clean, then wipe with a damp cloth to re hydrate, hey presto! Sticky again. Obviously the more you let them dry out, the more moisture they might need replacing. Common sense and experimenting. If you kill the pads, you can get them in packs of thirty or sixty right on Amazon. Round about a tenner, scroll up n down for the ones that fit your budget. If they aren’t passing a charge through, and you think they have stopped working, more than likely the adhesive gel pads have simply become too dry to conduct. Read instructions, research, experiment. Easy to use. Charge, clip on, slap on ya body, and twitch away 😉Update. While the pads last longer with regular hydration they are by no means a permanent piece of equipment, purchase spares and you’ll be sorted.Update. I stand corrected. After a lot of (heavy) use, the distribution of current DOES reduce, it is dramatic and uneven. I have checked the units, there are three clip on USB charged units, each works fine on one arm pad, but the energy transmitted to both the abdominal pad and the other arm pad is now negligible. I will contact the supplier and update as necessary. It has to be said, I’ve had about four weeks of use of these pads twice a day, but expected this to be a permanent piece of equipment.

Not powerful enough had to crank it right up but still not strong enough. I will be looking for a better product

Not tried this product yet but already disappointed, only came today and I had previously googled top ten abs belts and this was number 1. How I will never know hope it gets better when I use it, the instructions are as useful as a chocolate tea pot, it all feels really cheap, and I don’t not understand how the adhesive pads work

First time user of these devices

Doesn't have a great power

This is not the full kit. You need to buy extra pads as they only send 2 and this may work for the arms...well...one arm, but not for the abs pictured which needs a lot more. Also the instructions are translated very poorly ( from Spanish?) and don't make sense, e.g."when charging the indicator light is red and full of green"!! "Use the body parts that you have used to clean the pads"?? "Fruit, such as pressure, squeezed and hands"???There is no help with positioning eg on arms. Very disappointing.

I tried this today and wow my arms started moving with every pulse,like my whole arm with just the bicep attachment on setting 1,was very strong pulse,afraid to try setting 2,the ab part was much less intense and was able to use it on settings 3 and 4 for about 20 minutes,If u change intensity during use it resets the 15 minute timer for when it's meant to auto shut off for safety,saying that it says you can use product 2-3 times a day.the adhesion seems to be good so far.The instructions are bare and mainly gibberish,very poor translation to english.ex. in product features "fruit,such as pressure,squeezed and hands",rofl.
