I discovered this massager at a Cub Scout camp I was attending with my son. After trudging along dusty gravel paths for 3 days, my feet were in need of some relief. One of the camp leaders set up a parent recovery area and had the foot massager available for use. I hesitated at first, but eventually gave in and tried it out. Even with my shoes on, the relief was near instant and my feet felt great for the rest of the day. Once I got home I quickly ordered my own and have been using it almost daily. The foot massager really helps with my plantar fasciitis pain and lets me stay active. I haven't quite found the same level of relief using the body massager, but I don't mind using it.
