The listing, Rechargeable Massager with Sticky Pads has ended.
Thought this would help with the stiffness between my shoulders. Tested it out on my arm (did not remove sticky backing on pads), but it was so cumbersome for me to try to adjust the settings (thinking I could not see it on my shoulders), when I accidentally turned it up high, it was quite a shock. Like a Tens Unit, but smaller and portable.
