Review on MegaWise EMS TENS Unit: 48 Modes, 10 Premium Pads For Back Pain Relief Therapy - Dual Channel, Home Use With Gift Options by James Daniels

I always have shoulder pain and this Megawise portable massager is really helpful for me. Easy to use. You can even use while you are doing your other household stuffs. Instruction is very clear. The sticky pads comes in different sizes and shape and it also comes with the instructions of where to place on the different areas of the bodies. And you can use 4 pads at a time. Very powerful for such a small machine.
