Too bad, I returned after a test for two days. I was hopeful that it would contribute to the relief of my pain in the trapezius but the product does not allow ergonomic shoulder massage. It is, however, a good cushion that is well finished, velvet touch, touch control, easy use and immediate implementation. Good performance in the back in general, is ideal for a massage from the loins to the middle of the back. Both directions of rotation, so no need to return the cushion is convenient, pleasant vibration and heating a little long to get up to temperature but effective From the shoulders, it gets complicated and I can not feel much, it does more mass. Regarding the neck, "fingers" do not even touch me. Since I had ordered for it, so do not suit me at all, I have returned.
