This massager has three heads, which is better than two heads. Whenever I use it when I'm tired, my body feels much easier and feels very good. Its design is very beautiful, and it feels good in the hand. I just love it. After using it for another week, since having it, the body is not afraid of fatigue. When I was exercising yesterday, I was a little tired. I felt much more comfortable with this massager. Sleep very soundly at night.
