Rechargeable EMS Abdominal Muscle Stimulator ABS Trainer Toner Fitness Belt

Expected to be with batteries. The batteries plus the fact that they can be quickly changed. And the built-in battery has a small capacity and will die over time. I was disappointed that there are no straps because they eventually begin to fall off from my skin. Slips as pads if you have oily skin-I recommend lubrication of the skin with a solution of salt before applying the electrodes and tie with an elastic strap.
I recommend combining with strength training.
Look for bandage straps. Booklets are not very informative, it is not entirely clear what electrode to glue, except for the press. From micro USB inagda nibble.
I do not recommend tearing off the electrodes-the gaskets from the device-they will break. Charging laces are short.
It would be better to put one wire splitter.
The current is weak.
Over time, I will switch to a wired or buy a professional device. It is, toy.

Thought it came with the machine, simple is according to the description

For now serves its purpose, different types of massages and speeds. I hope the product will last and not break fast

Arrived fast, somewhat confusing to turn on, the control has a power button but if you run out of battery in it, understand it manual is done by pressing the button and turning it off is in the-eye to be able to use it well

Only missing some indications in Spanish in the case that is necessary
