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

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.

Relaxing pain relief. Pads are comfortable and stay in place so I'm able to move and walk around my home and complete tasks without pads sliding and the cord is a good long length for sticking the device in your pocket and moving about comfortably. Pad stickiness doesn't wear out too fast and just about every mode option feels really good and purposeful, and the customer service contact actually responds and assist quickly. I rate this as a great purchase.

Add lower back flare-up recently to a repertoire of musculoskeletal issues, and I decided to get a TENS unit for home use. My chiro uses TENS in his physio therapy and it does wonders. This unit does not disappoint. There are many great videos with this product, well worth reviewing, esp. if you're like me and hate reading manuals. Very nice that so many people are sharing their knowledge and experiences! The manual, however, is a worthy read (Yes, I did read it :); p. 18 has a great pictorial list of all the areas the unit can target; p. 25 lists areas you should not use the unit which, to me, is a critical bit of info!; troubleshooting pp. 26-29; symbol list, p. 30. This little manual covers all of this and much more! All in all, the unit is actually very intuitive to use! Many modes to choose from, and once you decide, hold down the middle button inside the mode, timer and intensity button, to lock in your preferences. Holding this button down again will release the lock so you can make changes.A few things to note:- Set up your pads before turning on the unit, then turn off before taking off the pads. You cannot charge while the unit is in use. It will automatically shut down, a great safety feature.- Be sure your skin is clean and dry. This will prolong the life of your pads.- I found my tendency is to want to pull the pads off after use using the cord side, and this is a bad idea. Peel off from one of the opposite corners. The pads are very sticky the first use. Repeated use will eventually wear off the sticky gel backing, at which time you get a new pad. There is a plastic electric pads holder, a very nice accessory! Rather than put the pads back on the plastic, put them on this plastic holder, making sure the cord does not get under the pad. There is room to store 4 pads, front and back, or a long pad per side. This unit, unlike many others, comes with 4 large pads, a nice benefit for targeting large areas. Once you adhere the pads to the plastic holder after use, put the holder inside the plastic bag it came in. This will also prolong the life of the pads.- One nice accessory not always available, is a plug to charge using a wall socket. Easy enough to use the USB plug on your computer as well.- The unit is Not touch-screen. I prefer this!- Go slowly increasing the intensity as it can become intense quickly and cause pain if you are not used to higher levels of pulsation and massage. My first use, I only used one tick up!- I have not had the unit long enough for this, but apparently the unit holds about a 10hr charge, so it should last a good while before a charge is needed. The longest one sitting use is 60 minutes, starting with 10 minutes and settings up 10 mins at a time from there.- The unit is small, lightweight, and comes with a nice carrying pouch.Here is a product page for replacement pads that I ordered, https://www.amazon.com/dp/B0CPXRHGJ1.

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.

This unit work fantastic on my shoulder/neck pain. I really like how it has two different channels, so you have have different setting on each one. The TENS unit is very user friendly and works exceptionally well. I use this unit ar least once a week, and I am beyond pleased with the results I get. Highly recommend for muscle pain relief.
