AUVON Dual Channel TENS Unit Muscle Stimulator Machine with 20 Modes, 2" and 2"x4" TENS Unit Electrode PadsCarbonfree Certified

I bought this on the recommendation of my doctor as I struggle to heal from a back injury. I was surprised because I assumed these units wouldn't work. I was so wrong! The contoller has two ports (that are controlled separately), multiple settings, adjustments in the power levels of each setting and a timer. To me it feels as powerful as the commercial model they use at Physical Therapy. The pads are thin so they fit under my clothes AND the control unit is pocket sized so I can walk around while using it. There are lots of models with widely varying prices. I am very happy with the quality of this one. The instructions are very clear which is helpful because I found it to be a little complicated. But once I followed the instructions it made sense and I find it easy to set up.

This unit is pretty powerful for being so compact. Having dual leads is nice option to help target multiple areas at once. The wires are secure and built into the leads. I feel like this is a better design than the wires that clip on to leads. It has multiple settings so there is something for each problem area. It works well for my shoulder and neck issues. I would definitely recommend this device!

Very reasonable price I like it so far. But I sure wish they had a static setting because you're sitting there all of a sudden you don't think it's working and you turn it up and then you get the surprise of your life within five seconds I don't like that, but from what I understand the research that I did, there are not any static settings anymore like my old one used to have

Sorry for the long review and rambling, but this tens unit has caused a lot of confusion, and me being a curious little Hobbit, I can't *not* say it all.I cannot figure this thing out for the life of me. I've read the instructions so many times. I've had 2 of the other 6 setting cheaper ones of the same brand where you can't control the different sides (A+B), and I didn't even need instructions to figure that one out. On the instructions for pad placements, some pads are shaded. There's no indication on what that means, but chiropractor told me to crisscross them and I'm guessing shaded pads on the diagram are from one wire. The cheaper one was soooo easy to understand, but this one, not so much.I took pictures of how he had the professional one in the office on my back when I saw him 18 months ago then bought one for at home. He explained how to do it myself in detail so my dumb blondeness wouldn't cause more damage or injury to my already wrecked back. I'm 36 and I'm too young to hurt like this *sigh* BAD car accident. These instructions seem to be backwards on some of the placements from what my dude said. He's been a chiropractor and owned this office for like 20 years so I trust him more than this booklet.I think I might just do it how I was taught since I have no idea what the mode numbers mean... they don't really point to anything specific. What does the 1 and 2 mean? No specific instructions. Maybe like on mode 3/4, the "1" means 3 and the "2" means 4? Are A and B supposed to be on the same 1 and 2 of each mode, or the opposite? Does A and B have to be on the same mode if they're in the same spot, like my lower back? As in, putting A on mode 4 and B on mode 13?This modeI, the instructions should be more detailed since the others are so easy, this one has way more buttons and SO many settings. It works a lot stronger (maybe DEEPER is the word I'm thinking) with the modes which are the same as my old one, that's for sure, but the pain was gone in 30 minutes with the other one and with this unit it seems to take longer for pain to subside. I might try an ice pack and thin towel on top like the chiro does in office, he recommend that for my home use too.I wish I wouldn't have accidentally ordered two of them, but for the price it's okay. My best friend has more pain than I do, everywhere, so early Christmas I suppose? I'm too lazy to return it and I love her face. I might update my review with her thoughts when she uses it. The battery lasted FOREVER without charging on my last one, hopefully this is the same. I'm really irritated that this one is a micro USB charger, my others from this brand are type C. Pads are more sticky than the replacements I bought for the other unit. Overall, I'm happy with it. I got it on Prime day deals for $23, I anxiously waited for it to go on sale for months.I'm definitely taking it with me to the chiro for an adjustment in the next few days so I can get advice from the man who knows all the things and the stuffs. For now, I'll stick to my old one so I know what I'm doing.

I hurt my back and was in excruciating pain. I tried the ice and the heat, and although they helped, my pain was still prevalent. I ordered this machine, for about the cost of a co pay, and it was worth every penny. The unit was delivered the next day, thankfully, and I charged it and used it immediately. The machine was nicely packaged and does come with a carrying/storage case. Everything you need for use is included. I was pleasantly surprised by the power supplied by this portable machine. I used it several times a day for several days and didn't need to recharge it, so the battery life is definitely good. The unit is small, so you're able to carry it around, I had it in sweatpants pocket, and it wasn't a bother at all. The unit has different programs, and I tried several out, liking some better than others. I believe that's a matter of preference or injury. This unit is functional and I was happy with the value. I believe it aided in helping me recover more quickly. I would highly recommend.

This little machine helps with pain. Has so many different settings and levels. I love it! I have hip pain and lower back pain alot. I put this on and it helps out tremendously! I do all different levels for like 20 to 50 minutes at a time. If your in pain I would definitely purchase
