Review: Love it!! - 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!
Review: Great stim unit - My daughter used this to assist her dorsiflexion to regain strength following spinal tumor treatment. Worked great. I should know I’m a PT

## Features

- TENS: "Transcutaneous Electrical Nerve Stimulation"- a safe, non-invasive, drug free method of pain relief used by Physical Therapists and professional Doctors for over decades. By delivering stable pulses to the skin to stimulate nerve fibers, Tens unit could effectively block the pain signal to people’s brain. At the same times, increases natural endorphins, which is a natural pain reliever. In many cases, the reduction or elimination of pain lasts longer than the actual period of stimulation.
- EMS: “Electrical Muscle Stimulation” is an internationally accepted and proven way of treating muscular injuries. It works by sending electronic pulses to the muscle needing treatment; this causes the muscle to exercise passively. When the muscle receives this signal it contracts as if the brain has sent the signal itself. As the signal strength increases, the muscle flexes as in physical exercise. When the pulse ceases, the muscle relaxes and the cycle starts over again.
- iSTIM EV-804: Digital TENS EMS combo stimulator comes with 2 channels, 5 TENS modes, 2 EMS modes and 24 preset programs, sending comfortable impulses through the skin that stimulate the nerve fibers in the treatment area. Effectively Block the pain signal to your brain! Safe and highly effective stimulation helps for treating chronic or acute pain (e.g. shoulder tension, back pain, arthritic, knee pain) and provides muscle relaxation and muscle strengthening.
- JAPANESE ELECTRODE PADS: High-grade, and biocompatible SEKISUI Japanese gel, which facilitates efficient conducting of the electrical stimulator’s current to the patient’s skin in a dispersed manner. 100% SEKISUI Japanese Gel is the harmless ingredients and the best fit for even sensitive skin users. Use the iStim EV-804 with our best electrodes, making your every pain relief treatment more effective with perfect and comfortable experience [NOTE: DO NOT USE Extra Electrode Gel]

### ⭐⭐⭐⭐ So far impressed...
*by J***H on November 1, 2019*

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.
