I really liked the thing!!!! Mechanical, without batteries, network, cords and noise! Very ergonomic design, conveniently lies in the hand! Excellent wrinkle fat folds, good for all parts of the body. Successfully copes with a massage of the neck, shoulders, arms, chest (these are parts of the body, which are usually difficult to massage with devices). The essence of the work is as follows: in the space between the roller balls (due to their faces and the angle of inclination) falls the skin with subcutaneous deposits and armisses there. There is a manual in english. It indicates that the massager uses solar microcurrents to activate cells, metabolism and blood circulation (it is logical to assume that lymph too). I am delighted with the ease of use and sensations! Massager cool! Recommend!!!
Everything's fine. I like it. Fast Delivery. I recommend.
