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

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.

Back on 2024.03.29 I purchased the iSTIM EV-805 TENS EMS unit as a logical upgrade to the TENS-7000 unit that I have had and used for years. As such, it is a useful unit having two additional output channels, a 2000mA/h rechargeable prismatic Li-Ion cell, EMS functions in addition to the usual TENS functions, and discrete step push button controls have replaced the old potentiometer controls of the earlier iteration of the device. A few friends have had their own units with them when visiting, and their reaction to comparing theirs against what I ended up using has always been favorable. I figure that people should use what they like and be happy with what they have, but several visitors have gone home and purchased this unit to replace their own shock boxes that look like iPods. Controls are intuitive and the display has enough contrast for my eyes. Normally, I prefer the newer black background, reflective characters LCD panels, because they are easier on my eyes, but have not had any problem reading the panel output during setting and use. Those two additional channels certainly speed things along, as opposed to shifting two channels from side to side. It is a keeper....after a couple of minor modifications: Firstly, anything that comes with an internal Li-Ion cell, comes with a cell capacity which is just enough to make the device functional for a token period of time. Nearly every manufacturer chintzes on internal power sources, and this device is no exception. Fortunately, there is more than enough internal space within the case to remove the 2000mA/h afterthought of a Li-Ion cell, and replace that with a 7200mA/h solution which yields acceptable use times, for around $4.90, and about 125 minutes of time spent massaging the case to fit the new power cells. Secondly, in today's retail market, I have trouble understanding why so many device manufacturers are still clinging to using legacy USB-Micro B connectors for charging purposes. Switching this device over to a USB-Type C connector for charging is a $1.25 line item ( in the retail market), carrying less than 10 minutes to make the switch, if you do it at the same time you switch out the power cell. Interestingly enough, the case does not need to be modified to accommodate the change in connector profile. The price difference between USB-Micro B and USB-Type C connectors being literally pennies on the manufacturing side makes the choice of USB-Micro B over USB-Type C for contemporary products ridiculous in the extreme. Lastly, I noticed that several customers mentioned missing character segments in the display of this particular model. While I had the device op[ened up, making minor adjustments, I happened to notice a significant number of screws missing. Since the missing screws were intended to hold the printed circuit board in close contact with the inside surface of the forward case half, it is likely that this could be the root cause of these display abnormalities. Having plenty of screws of the type that are necessary, I added them to the unit that I had on my desk. Upon completion of my fiddling around with the innards of the device, I powered it on, and noted that the display contrast was far better than it had been when I initially powered it on, so this tends to bolster my impression that this device, while good in intent, does suffer from unnecessary cost-cutting strategies implemented during manufacture. Hiring a competent and savvy plant rep would be a strategic move if market presence over time is desired on the part of those contracting for the production of these units. Despite tyhese minor foibles, the product is worth owning, and serves the intended purpose well.

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.

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.

I am loving this rechargeable digital TENS stimulator. It sends impulses that stimulate nerves in the treatment area to block pain. It comes with 4 channels, 5 TENS modes, 3 EMS modes and 24 preset programs. It’s just what I needed for my bad back!

This is my 2nd tens unit. This is excellent compared to my last one. I've had back surgery and this gives me temporary relief. Don't sweat much or the electrodes fall off. But are reusable .
