It works perfectly with my TENS unit!
One of the leads for my TENS unit had a short in it and for the longest time I just accepted it and would have to tape it and move it around to get it in just the right spot so it would work.  Finally I'd had enough and decided to order a new one.  The 1st one I purchased, off a different website, did not work at all.  I was pretty discouraged & dealt with the faulty lead again for some time and then searched again for a new one on Amazon.  I was SOOOO pleased with this one worked!  Aside from it being just a little bit shorter than my other leads, the fault one and the one still working correctly, everything is exactly the same and I couldn't be more pleased or thankful that I was successfully able to find  replacement.<br /><br />On a side note: I was able to find the part numbers for everything by doing a google search a long time ago, before the lead began shorting out, and found a reference chat showing what other parts could be used if I wasn't able to find the actual part I needed.  I'm sure that website is still there so if you're needing to replace any parts on your TENS machine and can't find the one you need, try doing a search with any information you have on your TENS machine and include replacement parts and hopefully you'll find the website I found.  I hope this helps!
