I like using my Livia device to avoid having to use painkillers entirely or on a less frequent basis. It takes a minute or so for the pain to lessen but it's great once it gets going. I do wish the clip was a little more sturdy and that the cord wasn't blaring white against my work outfits (all black). Overall, the Livia does the job it intends to do (basically a more compact TENS unit).
Pros and Cons:
Bottom Line: Yes, I would recommend this to a friend
