This percussion massager is awesome! I am a big guy, and really need a strong massage to get any relief. In fact, I usually have my wife stand or kneel on my hamstrings in order to get a deep enough massage.
This massager gets very deep and doesn't show any signs of being bogged down even with increased pressure on any of the 5 settings.
I also love that it is cordless and easy to use. Highly recommend!
