This is my second TENS unit and this one is much more powerful than my last. I really like the different modes and actually appreciate the informative emails on how to use the device the best - which I thought was going to be SPAMMY at first. Very happy with my purchase.
Well I've only used it twice so far but am definitely happy with its functionality and power, but I do wish it was rechargeable!
Don’t know how I’m supposed to to review when only had for less than a day but yet companies these days want reviews so there it is.
Works great, immediately gives relief!
