Quality is excellent! All buttons, everything works. I bought the most expensive on sale for 2100 rubles approximately. In the kit a cord for an outlet, a cord for a machine, two identical instructions (why two i did not understand), the massager itself. Buttons only six: on/off, direction of rollers, rotation speed, heat, memorization of functions and some other incomprehensible :) material under the skin, looks expensive, i really like! Delivery by the way was a courier to the door, which i really liked! And the seller put a gift :) I hope everything will work well, bought for a gift
