This little tool has been a lifesaver. I use it on my low back and when I have muscle cramps in my legs. It has lots of settings and the other tools in the box also come in handy. It is great for travel small and compact but very powerful. I give them as gifts as well.

I've used this several times already and it provides relief when my shoulder muscles are all stiffened up, or after a long day and my backs hurting this product makes a difference for me :) I have not had to charge it and ive had it over a month.
