iSTIM EV-804 TENS/EMS 2 Channel Rechargeable Combo Machine Unit - Muscle Stimulator + Back Pain Relief and Management- 7 modes/24 Programs/Backlit (Including Electrodes Pads)

I suffered a muscular back injury and this device helped with the pain and healing! its high quality and better than cheaper options. i reccomend getting the upgraded pads, they work amazing with this device

Make sure you charge this before using. It took almost 8 hours before the light went from orange to green.At first I was skeptical on how well the item would work. Set up was not very hard and finding the right modewas the kicker. Just make sure when you reach the setting right after ramp 2 you turn down machine. That's when i found the constant mode. All electricity all the time. It's now my favorite setting. The pads are well made and the wiring they give you is not hard to figure out so hooking every thing up was a couple minutes. I also saw a couple you tube videos to get the idea of the machine. I have used the machine and the same pads 4 times. It seems like they might stick well at least 2-3 more times. They do give you 8 pads with the machine.All in all I am impressed with this machine and it feels like I got value for the price.This was a quality purchase.

I've owned a sub $30 dollars TENS unit for about a year and it has been fine and a value for the money. I decided to try this unit as it has dials for intensity control, EMS & TENS, and rechargeable. I was immediately impressed by the quality of the electrode pads, they are way nicer and usable/reusable than the ordinary ones I've been using. Operation was fairly straight forward and control of the intensity is so much better with DIALS rather than push buttons. Jury is still out but I think this is going to be a nice upgrade from my previous model. I will update review at a later time.

Very powerful TENS unit. Works very well. Would be nice if a case was included. Overall very happy.

Love, love, LOVE this little TENS/EMS unit! It's perfect for what ails both me and my hubby. One reason a star got knocked off is that the directions are confusing and it doesn't explain what the symbols mean in a way I was able to understand. Had to watch a few YouTube videos of a chiropractor explaining what width, pulse rate, etc. were. Once I got the gist of it, everything else was very, very simple. I do wish that the electrodes didn't use the pigtail leads and just snapped into place. Hard to push the metal part into the black part of the electrode due to wrist pain, but eventually was able to get the wire to go in. Attaching it to my shoulder where I'm experiencing the most pain was a little bit of gymnastics, but I was able to place the electrodes in the correct spots without assistance. Electrodes stick very well the first and second time, but then start to lose their adhesion ability the third time so had to switch them out for fresh ones. Thankfully the unit came with extra electrodes, and I also ordered a whole bunch extra, too because I know up be going through them quickly. Hubby and I were fighting over who would get to use the machine first on Sunday, lol, so I just went and ordered another one so we can do our treatments at the same time without having to wait on each other to be done. All in all, great little unit. Also showed it to my chiropractor and he says it's a great quality machine and he approved of it, so that's a plus. Very effective for pain and tension relief, love the different programs, and that you can customize the settings if you need something different. There are 12 programs for the TENS portion, and I believe there are like 5 - 10 programs for EMS. I prefer the TENS; EMS is a little bit too forceful for me at this point. I'll have my chiropractor adjust the settings on that part for me. After 1-1/2 months of intense shoulder pain and dealing with lateral Epicondylitis on top of it, I was actually able to sleep most of the way through the night this past weekend!! I was forgetting what actual sleep felt like without pain! Definitely a keeper and I recommend it to anyone who is on the fence about purchasing a unit like this. Best of all, the machine and the electrodes are FSA/HSA eligible, so if you have an account with either, you can just use that to pay for it. A receipt was not delivered with the unit, so I had to go into my orders and print out the invoice for both of my orders in case the IRS questions me about it.It feels so nice not to have to choke down more ibuprofen or naproxen. Those meds were starting to make my stomach hurt due to having to take them regularly. I don't need an ulcer on top of everything else I have going on!Thank you to Istim for making this wonderful unit!

I have had issues with my lower back for years. At times it would seize up and I would go to the chiropractor and pay them $50 a visit to put the tens machine on me to loosen the muscles. I bought this and it works great. It relives pain and loosens muscles just like the Chiropractors.I chose this one because it was rechargeable. The charge will last over 12 hours of use. You will need to buy new pads after using them 4-5 times, but I expect that is the case no matter what brand you choose.

I’ve used many tens units and this one is by far the worst one I’ve ever owned. I wish I would have tried it earlier so I could have taken it back. I suggest the ultima. They are user friendly and work great!

The leads have already stopped working . Bought more leads . Now the channel plug is broken and only has 1 channel . In another 30 days it’s gonna be done . Products like this should have a stamp for pour quality . Regardless of it being 80 $bucks which ain’t cheap .
