Large Well

First of all for the better:
-) The device seems pretty well made from the outside. The seams look good, mechanically should fit all there.

Here outweigh the negatives:
-) The massage power is very low due to poor programs. In program 1 there is a point (about 10 sec), where it feels really good, in between, there are around 2 minutes where almost nothing happens.
-) One of the two massage heads has failed me for around 40 minutes. After an hour break, we went again, suppose he has overheated (those things are pretty hot).
-) Every 15 minutes, the unit turns off, which is quite annoying.
-) It's pretty loud. With headphones, you can still listen to music or watch movies, otherwise rather not.
-) The power cable is quite short.

A massage of 45 minutes is equal to about a 20-second self-massage.

All in all, mainly because of poor performance massage, I sent it back.
