Was skeptical at first, but then it got to a sports fair can try. With your hands in the loops can control the position of the part well on the back and the pressure of the massage. The massage program changes every few minutes, and with it also felt the vibration and heat effect, the latter is not particularly intense.
It is nice that it is of relatively compact, but still produces a decent massage effect on the back and neck. For durability and service I can (still) do not say anything.
