I’ve only used it once, but I like the amount of pulses, modes and strength of the tens unit. It was very powerful and I see myself using it often. I’m going to use it on my mom when I visit her to see if it helps relieve some of her pain and if it helps I’ll get her one. So I’d definitely recommend it so far after only one use. Not sure how it will hold up, but I’m hoping I’ll have it for years to come.
