After having used an expensive TENS unit ordered, at my request, by my doctor after a major surgical procedure in 2008, I was amazed at the amount of pain it controlled right from the start in the recovery room. I was given Toradol for the first two days. After that, I was able to use just Tramadol for a few days, and then alternated between Tylenol and Advil when needed for only about another week when I went home. I never needed serious pain medication, which I wanted to avoid. I DO have a high pain tolerance, which convinced my doctor to at least try the TENS unit. It was wonderful!I don't have chronic pain, but I do have the tendency to stress lower back muscles, shoulder and neck muscles, and occasionally my knee, which has had three ligament surgeries. I never thought a TENS unit was affordable until I saw one featured here on Amazon. I then researched all the units offered on Amazon, and the iStim EV-820 had the best overall reviews from customers using it for more serious issues than mine. I decided to try this unit.I used it for the first time last night on the left side of my neck and my left shoulder, which were tight and sore from lifting things I shouldn't have been lifting. I read the manual thoroughly, and having used a TENS unit, I knew that the increase in stimulation has to be gradual to get to the level I could tolerate. Everyone one is different and tolerates different levels of stimulation. The manual recommendations are not a be-all for every user.Since I had some experience with a TENS unit, I did not pre-set the unit to the recommended level, but after adhering the electrode pads in the recommended places (which I later adjusted with no difficulty), I turned the dial and dialed up slowly to get just enough stimulation to determine which mode I wanted to use. Once the mode I desired was selected, then I increased VERY slowly the stimulation.I felt that the instructions, complications, warnings, and placement diagrams were clear, precise, and thorough. Every technology has a learning curve, and it is the responsibility of the consumer to read very carefully and ask questions if not sure about how to use any TENS unit.It was perfect for my specific need last night. I went to bed ache-free and slept well after a 30 minute treatment, a break, and another 30 minute treatment. I am glad I decided to try this unit, and I feel confident that future use will result in reduced, less potent medication or medication-free pain relief.

After a very intense search and reading review after review I decided to go with istim. I have an auto immune disease that causes my joints to swell everyday and fibromyalgia that causes me pain everyday all day and I’ve been dealing with it for a few years now and medication isn’t working Like it used to Plus I hate taking because of the side effects... I have used tens units before and they provide me with some relief from the pain that I am always in, but they don’t last cause they crack or just stop working so I’m hoping this one does. I love how compact it is and the case it comes with to put away or easily take with you on the go!I actually purchased istim because I needed a portable tens unit that wouldn’t fall off or turn off on accident. It has a plastic clear protector so you don’t accidentally turn the dials up & the instructions are clear and easy to understand, the best part is the placement diagram they give you for all kinds of areas of the body with chronic pain which I thought was absolutely awesome! I just wish it wasn’t battery operated. If it was rechargeable like a cell phone I would have definitely rated 5 stars!! It has so many different settings (WARNING!!! just don’t try to turn the dial in the dark, it’s a doozy!!! LOL) you can set a timer or not have one at all...which I prefer when my pain is so bad I can’t even brush my hair or get dressed. I like that it also has a clip so you can clip it to your pants, especially yoga pants! 😂**This is not a cure this is just a form of temporary relief for chronic pain and much better than damaging your liver with pain meds but I am in no way saying you shouldn’t follow your doctors orders 🤗

This TENS UNIT seems to be a great one for the price especially. I opened it up last night, it was packaged nicely and it is simple to operate, try the different modes out. I hope it last me a long time. I highly recommend getting the Auvon 2x4 pads for maximum relief. They are on Amazon and they are $9.00.

I read a review that said if you want something easily understood just by looking at it, this isn't the tens unit for you. They were so right! It is perfect for me anyway.I have used several tens units and they do a good job helping me with pain. Most have pictures and it is easy to scroll through different massages and increase the intensity.This one has no pictures and the only thing I have figured out how to do right is increase the intensity and set the timer to not shut off. My other units all have a 60 minute timer and then they shut off. My pain comes back instantly so the "continuous" or no shut off timer was very important to me and the reason I bought another unit. You can set it to turn off in 5 minute increments up to 60 minutes, if you wish. I will figure out the other modes and settings as I have time to read the manual.One word of warning. Setting the intensity first and then flipping through the modes is a big mistake. The first time I used it, I did just that. I had the intensity nice and comfortable and pushed mode. It's a wonder I didn't scream and wake the kids. Very painful. I learned really quick to turn the intensity on where I can barely feel it before pushing any buttons.I look forward to getting more familiar with the unit. If it works as well as it seems to after only using it for a couple of hours, I may upgrade to the 4 channel tens unit in a few months.
