MOOYEE Tens Machine EMS Muscle Stimulator Pain Relief Massager for Neck/Shoulder/Back/Mini,Loving Gift for Men and Women

Absolutely amazing. The device is very very powerful. There are loads of options to choose from. I love it so much I'm getting my parents one as well!Only one thing - it was really difficult to connect my phone to the devices. At the end I got the app right from the website.

Very useful and has many functions

ok, not brilliant
