Terrible after the first use. The glue did NOT work, resulting in it not doing its job properly.

I tried it and I would say that it can offer in terms of firming, slimming, muscle relaxation, and simple muscle maintenance. Unfortunately, the problem is not the batteries that can be replaced since they are common in the market, but the quality of construction, especially of the parts that are adjusted to the body. They break down after a few uses, and this unfortunately makes the device of limited use.
