Light, easy to storage
Specially great because is really light, no need a lot of storage place. It can work as muscle stimulator and as a pain reliever, one device that works for two, for me that fits better my budget. And I also can get control on how much therapy I can handle or I feel comfortable with. Easy to learn to use, just need time to adjust the frequency that works for everybody.
