I purchased the shiatsu pillow massager because I am tired of always going to a massage parlor and always end up paying a big amount of money. This massager is a perfect size for me. I put this on my back while watching tv, working on my computer or even sitting in the car (as a passenger).
It automatically turns off after 20 minutes to avoid overuse when you've fallen asleep. It is quite as well so it will not bother your quiet time.
Its warmth soothes my aching back muscles after a long day. This just helps me greatly!
