iSTIM EV-805 TENS EMS 4 Channel Rechargeable Combo Machine Unit - Muscle Stimulator + Back Pain Relief and Management- 24 Programs/Backlit (Including Electrodes Pads)

This is the best EMS/ TENS unit I have purchased. The quality is outstanding, it's easy to use, and it performs exactly as promised. You can tell a lot of care went into the design and craftsmanship. I would absolutely recommend it to anyone looking for a reliable, high-quality product. I'm very happy with my purchase and would definitely buy from them again.

I bought this for the EMS function. I've been dealing with a chronic illness for the last few years, and unfortunately it led to muscle atrophy in my legs because there was no way for me to be active. On top of that, one of the medications I tried for the chronic illness caused joint degeneration on my knees, so my ability to walk has been greatly decreased. My doctor recommended physical therapy, which I totally agree with but can't afford right now, so I bought this to help get some strength back in my leg muscles. I honestly didn't think it was going to do much, if anything, but if it didn't I'd at least still be able to use it as a TENS for pain. I've been using it daily for about a week on my quads, starting with my right leg because it's weaker than my left, and after a few days I actually noticed a difference! Son of a biscuit! It's so much easier for me to get up from a seated position, and I can actually manage going up and down stairs leading with my right leg now! I literally cried. I haven't been able to go up and down stairs like normal for about 2 years, and I was able to just the other day (still slow, but not one stair at a time like I had been doing). For reference, I'm in my mid 30s.That being said, the device itself is a bit more complicated than ideal. I haven't played with dialing in settings myself; I've been using the programs it has for EMS. Comes with a couple very handy diagram sheets with what program numbers should be used on what areas (one sheet for TENS and one for EMS), and each one runs for 30 minutes. So I hook up my right quad, and rotate through EMS programs for a total of about 2 hours a day. Much more than that and I need a day off because my leg ends up sore. After the initial charge, the battery has lasted a whole week of daily use (minus one rest day) and hasn't given me a low battery alert yet. I saw some other reviews saying they need to put the strength up to 8 or 9 and was worried that this device wouldn't be strong enough, but I had to start out at 3, lol. I'm at a 5 or 6 now, depending on the program.The adhesive pads are alright. I've had two other TENS devices with different types of pads; these are about average. The fabric is soft enough that it can contour to different areas without peeling itself off. The adhesive itself isn't anything to write home about; in one week, using one pair of electrodes at a time, I've about finished my second set of pads. I've been keeping the pads on the plastic sheet they come on and in a Ziploc bag between uses. I have *not* been wiping down my skin with an alcohol pad before use, so your mileage may vary should you choose to do that.This device is enough that if doing physical therapy seems impossible (physically or financially), this may give you the boost you need. It's also really easy to put on and forget about while it runs, so it won't interrupt other activities; the EMS programs don't cause my muscles to jerk like a TENS usually does. Overall, if you're dealing with muscle atrophy after illness, I'd say this is worth it. At the price of about 3 physical therapy copays it's not cheap, but it's enough to help me get to where I can do exercises at home and build myself back up.

A lifesaver for my localized back muscle pain. I use this nearly every night and would not be able to sleep without it. The different options are great, although I have stayed with the same one as it works best for me. Having four channels available to use at once. Thankfully, I rarely need more than one channel but it is great to have the additional ones available if needed. Battery life is excellent! I have this on for the entire evening and night at times when necessary (up to ten hours sometimes) and the intensity never wanes. I have yet to use it long enough for the battery to die. It also recharges to full capacity quickly. The only issue I have experienced with this unit is one of the input ports stopped working due to the inner part of the port somehow got pushed down in too far and didn’t pop back up when removing the wire. That is the only reason I gave 4 stars instead of 5. But, I still have three channels available, so it hasn’t been an issue. This unit is worth the price. I was spending a lot of money on 9 volt batteries on my basic tens unit. Not any more!

I bought this to help with low back pain and to rehabilitate some shoulder muscles after surgery. With this unit, you can run 4 channels at once on the same program at varying intensities. It works well and can do several sessions without recharging.

Great quality and very easy to use. It helps relieve muscle pain and tension effectively, and the rechargeable battery lasts a long time. The multiple settings are a nice bonus. I'm very happy with this purchase and would definitely recommend it.

Arrives in a very nice Apple-like white box. Very well packaged and presents as a high quality product. Instructions and such are quite a read. This thing is fairly complicated in operation with bunch of different settings. There's a learning curve here to be sure. Did best I could to understand how it worked. So got two of the skin pads out, hooked up to Channel 1, placed them on my lower thigh and upper thigh. Program 20, level 40 intensity. It definitely puts out some electrical stimulation. Over the next week or so, I'll figure out more about fine tuning pad placement and such. Overall, the unit is very high quality construction, is very solid. I'm using this more for rehabbing my leg muscles due to neuropathy and we'll see if it can help.

I bought this in 2018 and I'm using it right now. I get a full week of use out of a single charge. In fact, I've never run the battery dead completely.I chose this model because it has 4 different channels, they are individually programmable, and I can change the frequency of the impulses and the width (meaning depth) of the penetration.The max timer is 60 minutes, or it can be set to continuous.I saw one review complaining that they "felt nothing at level 4," but this unit goes from zero all the way to 100. I bought it for pain relief. If the electrodes are brand-new, I definitely would not need to go over 20. I have never used power level 50, because that would be downright painful. I can't even imagine maxing it out to 100. I have no doubt 100, with an EMS setting, will contract the largest muscles.Yes, it is a bit more expensive, but I only want to buy one thing one time and I don't want to buy a lower-priced unit, then find out it's lower-priced for a reason. One fixed "pain relief mode" does not feel the same to everyone. You WILL have to read the manual, though, if you want to get the most out of it.

GET THIS!!!I've used tens machines before but this is the best one ever. I got this after spinal fusion surgery, to replace my old one that broke. It's perfect! I have no cons, only pros.IT IS VERY EASY TO USE! Just put the pads on according to the included chart, plug the cord in, and turn it on. Check with your Dr to make sure the settings you use are ok. I use it for pain relief and to help stop muscle spasms. I keep it on tens mode, program 1 all day. It really helps to reduce spasms frequency and intensity.My mom and I both have muscular dystrophy and injuries to our backs from car accidents. I just had surgery to fuse my lumbar spine. She can't do surgery due to other health issues, so I let her use this a few hours and she felt MUCH better.This comes with a bunch of pads, but you can use them over& over so these will last a really long time.The battery lasts forever. I use it a few hours daily, and it still keeps going for a good 2 weeks. When you do need a recharge, it goes fast. The case it comes with is ready to toss in my work bag. Cables are long, and is you do want something different they are easy to get at medical supply places or online.TIPS: Make sure you have no creams or lotions on the pads or skin placement site. Keep at least 1 inch between pads. DO NOT LET THEM TOUCH! That hurts, and it can short out the machine.When you remove the pads, don't just pull the cable. Hold the pad and the cable firmly and peel it off. The adhesive is strong so it can be tough if you don't have enough hand strength to cut a steak. Don't let the sticky pads touch each other. Follow the pad chart... You have to put the red and black parts in the right spots, not too close & not to far apart. Put the pads on, and THEN plug them in& turn on the machine. It hurts like hell to try to move them with the machine on. During use make sure the whole pad lies flat on your skin. When they lift part way they sting pretty bad. Most important of all, start out slowly and show it to your Dr and/or physical therapist. Both can show you how to set this up safely.The EMS part works differently, and you can actually pull a muscle if you do it for too strong or for longer than it tells you to. So be careful. You won't get all 'bulked and buff' by using it lying on the sofa all day. But it will strengthen you enough so doing walking or PT exercises don't hurt like crazy. You have to get up and move to get better.Good luck and if you get this I'm sure you'll be very happy!
