Product is great and easy to use. Easy to hook up to phone. Many types of good settings. Packaged well.Amazon delivery should only get 1 star. Changed delivery date later than expected when purchased and was needed for medical problem.

I've had this Comfytemp unit for over a year now. I am very happy with this wifi cordless unit. It works great and the price is right. I have used it for muscle kinks and osteoarthritis in my knee.Con- not happy with the reusable pads that come with this unit. They are cheap, don't last very long. I found another company on Amazon that sells replacement pads with snaps. I buy those pads instead. They are made of a heavy duty vinyl pad. Can be used many times before having to replace them.

This is the most powerful TENS unit I've ever used. I rarely turn it up to even 50% power. The batteries in the devices also last a long time which lets you focus on restoration and not on charging. I like that it also has EMS and massage modes. It would be nice if you could control whether or not it goes in a pattern or goes continuously. I bought an additional set and for some reason, the app does not allow you to use more than two units at a time which is frankly stupid. If I want to run 8 of these at once I should be able to. There's no good reason to limit it. Please change this and I will buy more. The other thing I don't like so much is the pads lose stickiness very quickly compared to other pads I've used. You get a few uses out of them and have to buy new ones which can get expensive. Luckily these units are an amazing price for what you get. More options than the two pad types would be nice as well. They're both pretty small so a larger one would be nice. Another nice to have would be a slimmer main unit. Even if this increased footprint size I think it would be worth it for comfort. Lastly I would love a version with heat. I haven't been able to find a single wireless unit that offers that. It's hard to find them even in wired units. So make it happen. Overall it's a nice unit and works well despite the few gripes and nice to have wishes.

We absolutely love this tens/ems unit! I was not expecting all of the settings, all of which are great! It's extremely easy to use, from attaching the pads, to using the app! We love it so much, we are planning to get another one, very soon! The pain down my leg, from my lower back, is so very much better now, I won't be going back to the pain specialist! Thank you!

I used to use the icy hot smart relief tens unit. This unit is easier to use than that. So if you’re familiar using that one, this one does much more.The app is easy to use, it’s nice to be able to turn on and off from the app and adjust the level. Battery life is really good, it’s easy to charge. Comes with a nice case that fits all the pads. The pads are the perfect level of stickiness to stay on and be effective, yet easy to pull off. App allows you to control both units and have different levels of intensity with each.Definitely recommend this unit, can’t wait to explore the other features.

Great performance for the price. Easy to set up. Not sure how long the pads will last. Wore to work and used throughout the day. Great battery life

I thought this would be good, but it's not.The base layer of the pads is made from a semi-rigid plastic. The edges are sharp and they chafe the skin the entire time they are on. Plus the wire on one of the 2-piece pads broke off the first time I tried to use it.Also, the control app is not user friendly. It allows you to use 2 units at one time, but you have to have both of them on the same setting. So, if you want one on your back, and one on your leg, with the back set to one setting, and the leg to anther - you can't. You can set the intensity separately for each, but that's it. The type of setting (tens, ems, tapping, needing, etc.) is set to the same for both units.And, if you go through a cycle on both or either of the units, and then want to set up another cycle, you have to back out of the app all the way to the first screen, turn both units back on manually, and then go forward in the app to the setting screen. That's the only way the app will resume communication with the units.

I get terrible tension migraines and desperate to try anything to make them manageable.I like ALL the different types of modes on this unit. It’s has repetitive options as well as long routines.The different intensity levels are effective and use them frequently. I also LOVE that this is wireless. What a huge advantage that gives you.I have one huge issue with this unit though. The pads are too big and not sticky enough. They are so big there isn’t any flexibility either. They are designed for large flat surfaces only and not for natural curves. I use this on my neck and shoulders and the pads are just not flexible or small enough. I ended up taping them down. When taped i love this thing.The stickiness does not last either. Even taping down isn’t always effective since they do need to stick well to your skin.All in all, i like the different nose enough to struggle thru the massively poor pad design. I tried other units and keep coming back to this one for the range of options it offers.I wish they would redesign the pad options to different sizes and something more flexible that sticks better. I would pay double or triple for that, that’s how much I love this unit.
