iReliev TENS + EMS Combination Unit Muscle Stimulator for Pain Relief & Arthritis & Muscle Strength - Treats Tired and Sore Muscles in Your Shoulders, Back, Ab's, Legs, Knee's and More

This is the best Tins unit I've ever has works great

I currently own 2 iRelieve tens units. One that takes AAA Batteries and one that is rechargeable. I have rechargeable Panasonic Eneloop batteries (which are fantastic) so I am comparing the functionality of both units. First, both are FSA Eligible which is awesome! That being said the buttons on this unit have held up extremely well and is made much better than the rechargeable iRelieve tens unit (buttons that don’t push in are pictured). I have had both types of tens units for over two years and the rechargeable unit recently started giving me issues. For example the buttons on the rechargeable unit are piston push like the tens unit that takes batteries, but the pistons stopped working on the cheaper made rechargeable unit. For now when I tap on the buttons the rechargeable tens unit the function works but I believe it’s only a matter of time before it stops working completely. As a result, I think the battery powered iRelieve tens unit is much better constructed and far more compact than the rechargeable version. And now is a great time to invest in rechargeable batteries, like the panasonic Eneloop batteries as they have lasted me over 5 years and still going strong. Reusing the same batteries has to be better for the environment right! Overall the battery powered version is more compact and made far superior than the rechargeable version at equal price. The pads are a 3 out of 5 as far as adhesive but I don’t think you can do any better right now. I haven’t found extra strength adhesive pads and don’t think they exist yet. The pads are basically made to be used while seated and keeping movement down to a minimal.

I thought I was buying a rechargeable unit because that’s what I wrote in the AMAZON SEARCH BOX. Not the fault of the company who makes this. I’m sad because I had a bunch of leftover snap electrode pads and I can’t use them with this unit unless I buy some adaptors from pin type to snap. Even then I’m not sure it will work.I’ve had to look up videos on how to use it, because I didn’t get an instruction book.The videos on this unit say that there are 13-14 different modes on TENS but I can only get 8 modes on TENS. That’s annoying.I’ve had to purchase small electrode pads separately because the pads sent with this were all big.At the end, it works ok and was totally worth the price.just make sure you look at all the pictures and read the description before buying it.

Bought this for chronic mostly muscular back pain.The main control unit is pretty small, about 2 x 3.5 inches. Comes with 3 AAA batteries. Hardly weighs anything even with battery installed. Display is good, but is not backlit. There are 2 electrodes plugs on top. Each electrode split into 2 pins that plug into the contact patches. Electrical current cycles between the 2 pins, causing the EMS or TENS effect. You can run one electrode at a time, but that electrode has to have contact patches plugged in in order to work. You get 4 packages of contact patches. The first two packages each have four 1.5 inch pads. Again, you'll need 2 patches per electrode. The patches have a sticky adhesive and comes stuck on a plastic sheet. You remove the pads, plug it in to the electrodes. When done you peel it off your skin, then stick it back onto the plastic sheet for storage. According to the label, each pad last up to 30 uses. The second set of two packages each contain 2 larger contact pads that measure about 3 x 5 inches.Usage is super simple. The manual is excellent. I looked at it briefly. There are 2 basic modes. TENS and EMS. There are 8 preprogrammed TENS modes, and 6 preprogrammed EMS modes. The manual does a good job differentiating the different modes. There's no way to program you own modes. Each electrode has intensity setting that goes from 0 to 25. Then the last function is the timer. You can set the duration of use, and the unit turns off afterwards.I've used this now for a couple of days. What's it like? First the TENS modes feels almost like tiny needle sticks that cause a tiny bit of surface muscle fascination The EMS modes feels similar, causing mostly muscle contraction, but not so much the pin prick sensation.Does it work? Frankly I've not used it enough to really say. Though this technology has been well researched. I do feel that my muscles are just a bit more relaxed and I do think I feel less pain. It's not an astounding effect like taking a good pain pill. But I think the effect will build over time.Overall I like the unit. It does what it's designed to do. It's easy to use, small, and relatively inexpensive. Apparent quality of the unit is good also.
