This is the TENS unit I own. My first one quit working. I replaced it with a cheaper one that lasted a lot less long. Then I reordered this one. I'm happy with it and use it for the peripheral neuropathy in my feet and carpal tunnel in my left hand. I also use it for my calves and thighs for circulation and cramps. I had treatment for breast cancer (now in remission for almost 2 years) and the peripheral neuropathy was caused by the chemo.The TENS hasn't been able to get my ability to drive back

If this comes through gobbly-gook, I bought th Massage Therapy Concepts for around $69 on Amazon
