Excellent product! If anyone gives it less than 5 stars then they expected way too much. I bought a tens unit years ago, and it was not nearly this good. I used this product once and all the tension in my neck is gone. Do yourself a favor and get this unit. You will not regret it.

We already have another two tens units, small ones we purchased from Walgreens. This unit is the same price and is so much better. We love the setting and the dual zone control. Wonderful unit, good strength, pads are very sticky. Very happy with this purchase.

This was recommended to me by my daughter-in-law who happens to be a nurse. I had knots in my muscles and this unit did an amazing job at relieving my pain. It is easy to use and can stimulate two areas of the body at the same time with multiple functions. I absolutely love this unit and so does my wife. Well worth the few dollars that it cost!

This unit works amazingly well. Holds it's charge for several sessions and very powerful. For the price, it has far exceeded my expectaions. I actually purchased 3 more for family.

This little guy is incredible. It's smaller than a cell phone and light as can be and is really powerful. If you have had it done at physical therapy and think that because this one is small and battery operated that it's going to be bad. No way! So far what was on an 8 at physical therapy is on a 2 on this machine. Battery lasts what seems like forever. The screen is very plain but very simple to use so no complaint there. Great buy!

This was to replace the old basic unit I had for 10 years. Great little compact unit that really packs a punch! Good quantity of pads, both large and small. Love that you are able to lock the screen. 'Downside' might be that if you miss your desired mode, you have to click a lot to cycle back through, there is no way to back up. BUT the cycles are all remarkably different, so I am very glad to have them. Really like having independent channels and the fact that it is rechargeable means I can use it guilt free to my heart's content! Really love this product.

Got this to replace my old TENS unit. I love that it is much smaller and easily charges via USB. I have multiple back issues and this helps alleviate some pain. It is not a miracle, but takes some of the stress from tense muscles caused from the pain of multiple herniated disks. It has multiple different settings and can go from light to intense. The charge seems to last pretty long. I just hook it up to charge after use, then put it up for the next time. Would definitely reccommend for anyone from first time users to people that have used before. Good deal for the cost. Comes with everything needed to charge, plenty of pads, a pouch to keep it in, and a plastic pad holder to stick pads to for next use. The length of the cables is good, long enough to be able to hook the device up and put it in your pocket so you can go about your life while in use.

I bought this item to help loosen up tight muscles in my legs and to relieve sciatic pain in my back. So far I am having great success with the unit. I am hoping it will continue to work so I can get around.

I slipped and fell on a patch of ice and hurt my shoulder I used the smaller patch on front and back and it has helped tremendously. Haven't tried all the modes yet but it's a nice little unit. This is my 3rd and my favorite by far

It came fully charged. Have used for approx 15-16 hrs before needing to recharge. 10 days with 3x30min sessions/day. I don't know what the specs are but I think this is pretty good. I am finally changing out the pads as well. I have used all 20 modes. I do have a few favs.
