I overall didn't enjoy this product because I felt that the pulsations were dull, and not at the standard that I prefer. I like vibrations to be quick and hard, not as a dull massage. We did find that it worked well as a massage tool for your body. It worked out knots in my husbands back and put him to sleep quite well. I never lost the ball because it was attached, and got in the way too many times before its face hit the wall in frustration.
