First unit not working properly but now problem has been resolved by seller

This a great item. Works really well and charge last a good few uses. I used this after knee surgery to help with recovery and was really helpful. I have used this about 20+ times pads are still working well.

Very complicated couldn’t not read instructions

This is honestly one of the best TENS Machines out there at the price point. The pads that come with it are very sticky and I tend to use it quite a bit. It's battery is easily charged using the supplied USB-C cable, and lasts a long while. It's quick and easy to use, as well as being highly configureable. The nicest part about it is that unlike cheaper TENS units I've owned and tried, this machine doesn't have the "sharp-stabby" feel which I'd put down to very good power supplying and monitoring. This also goes very high and hence can help with some of the worst pain. It can be locked too, hence making this a very pocketable unit.

This is a great unit with very good power output and a great battery life. However, I have now had 3 of these units of which none of them work properly. All 3 units had power going to 2 pads rather than the 4 the unit supports. Really disappointed as it's a great little product. The images below show the 3 model numbers of the units. Two are the same number and one is a different model number. In all cases only 1 pad each side received power.

I've always used tens machines with wires before and this is brilliant.

I had one of these like 20 years ago that worked fairly well, but it broke a long time ago. I bought another one off of amazon maybe 7 yrs ago and it was so painful to use, it just didn't work right. I was reluctant to try another, but knowing I used to have a good one and my chiropractor has a good one, I knew it was a matter of trying them and reading reviews to find a good one. THIS IS IT!!! I'm in LOVE with the way this one works and the features that it offers!!! I have mostly only used it on #1 because it's good enough to stimulate without over doing it. I tried bumping it up to 4 once, but it seemed to feel better on #1 or #2, so I went back down. It works well, offers pain relief, and I believe this unit is a Wonderful Value for the money when it makes me feel better!! I love the different settings, and what's amazing to me is that it actually feels just like the descriptions... it's like there's a massage therapist actually doing those things!! I don't know how they program electric-stim with that type of feeing, but it's just WONDERFUL!! If you want a good machine at a decent price, this is it! I can't speak for longevity yet; but so far, it's held the charge and I've used it several times on that charge, so it's good enough for me! I hope it keeps working for a long, LONG time into the future!!

It does the job thx

Ottimo apparecchio, funziona bene. manuale difficile da capire, tante funzioni ma non si riesce a capire cosa servono.

This is a really good unit with loads of different settings, got it for the wife to use on her ankle and she is very positive about it's use and thinks it's doing her good, so worth every cent. East to use as well, great quality, lightening fast delivery as usual from Amazon.
