ComfytempWireless TENS Unit Machine for Pain Relief, FSA HSA Eligible TENS Unit Muscle Stimulator with Two Sets, Up to 30 Modes TENS Device for Back Pain, Rechargeable Portable with APP Control

I had an old TENS system and found out recently that it was very ineffective because it was so low powered. I read about a famous maker wireless system but it’s very expensive…after looking online, a few “Best of” lists included this system at or near the top of the lists. I found it on Amazon, read some of the reviews and decided to try it. Firstly, it’s extremely affordable as compared to other wireless TENS systems. I used my HSA card to purchase it….no problem. It was also available for next day delivery and that was what I needed, as I have a chronic lower back issue and needed immediate relief. After it quickly arrived, I found it to be a great and complete system. It can be used either with or without the free app but the app offered more features and I like the interface as well. There are several pads provided for small or medium sized targeting and 2 wireless “pucks” that those pads attach to. The app has plenty of body zones to focus on, plenty of shock pattern modes and up to 20 levels of intensity. It is very small but very MIGHTY! I am using the single puck for my lower back spot at level 10 and that’s almost too high. I can’t imagine what 20 must feel like!!! Dang!! The pucks are rechargeable, have sound and led light confirmation on settings selections and can be easily charged with the dual USB C cord that’s included, I just wish it was a longer cable. Im very impressed with this system and no longer even interested in the far more expensive system that I first mentioned. I just hope they hold up well and the puck batteries last. So far I’m very impressed and highly recommend them to anyone needing a TENS system. Talk about bang for your buck!!

I use a tens unit almost daily for back and shoulder pain. I decided I wanted a wireless unit to allow more mobility when wearing it. I had read so much about poor battery issues that I spent $100 and bought a “medical grade” version. Turns out it had limited modes of operation and was not really what I needed. I decided to try this unit that uses my phone as the controller. Functionality is great and it allows many options in turns of pulse patterns and duration of the session. And battery life is excellent. I would estimate I get 5-6 hours from each charge. And it comes with two chargeable units. If you’re comfortable using a phone app as your controller, don’t spend more, buy this system.

Update: the company contacted me about the issues I have with this product. Very nice of them to do that.—The glue on the pads leaves residue on my skin.—I do not like how the glue feels on my skin while using the unit; almost a stinging feeling. Not comfortable for me. I am very disappointed ☹️.I have used many Tens units in the past and none of the brands of pads have left little balls of glue upon removing the pads.++The pads sizes are generous.++I figured out the wireless aspect on the app…not the simplest but okay.++Controlling from my phone made it even more portable.I won’t be able to use this on my scapula unless dear husband is home to put it on and take it off because I can’t leave the gluey pads on for long.—The wireless units size stick out quite a ways for example, on my knees. I had to be careful not to bump them.

So easy to use and works great! Not quite as powerful as I would like, but for the price and wireless is awesome. The only complaint I have is I wish I could control the two devices separately on my phone. If you use both, they have to be on the same mode and same intensity.

Still have an older TENS unit but the cords can be annoying when you want to move around. Wireless is a great solution. The app was tricky to get to work just right but once you figure it out it's simple. Only one bluwtooth connection so both units work at the same mode an intesity even thogh both show up on the app. The pads with the small cord work great as well. Strong pulse. The beeping is a bit annoying. Otherwise these work well. Great purchase.

I bought two of these machines for my knees. Unfortunately, where I work doesn't have good reception so I am unable to use the app. I constantly have to turn the machine on since it only stays on for a short period of time. The machines also fall off easily and the pads aren't sticky enough. It works as a temporary solution to my pain, but there needs to be improvement. This machine was the only that was eligible for FSA without wires and somewhat affordable, but just beware that you will need to buy more pads since they only last three-four uses.

Bought 2 of these not realizing they come with 4 pads each!!! Absolutely love the versatility of the different pads. Worth the money for sure, good quality pads have last over 2 months so far and use this regularly. Very sticky adhesive yet releases from skin easily

I'm pretty bloody amazed at these things (I'd say "shocked," but...). They works as promised, and do pretty well with my sciatica. Is it a "fix" or "healing"? Nope (no product can promise that). Could it merely be a *distraction* from the pain? Sure, but any modification to the pain is a welcomed relief. Good (surprising, actually) battery life. They stay in place well, as do the pads. The only reasons for 4 instead of 5 stars are the app—while useful—could provide a bit more control, and the charging cable could do with being a bit longer. Frankly, when they come out with a model that does wireless induction charging, I'm in. Time will tell on the durability question, but I will likely be buying another set of these regardless. They seem to be a GREAT value...
