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]

Safe, All-Natural, Drug Free and Long-Lasting Pain Relief. 510K approved for OTC use and safety regulations (IEC60601-1, IEC60601-1-2 EMC) certified. Made in Taiwan.

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!

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
John Smith –
So far impressed…
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.

Reduces muscle pain and helps tone targetted muscles
Absolutely love this device. My back and hip pain was caused by muscle strain and the pain is greatly reduced.The EMS is great for turning muscles back on after an injury and for targetting specific muscles. Not sure what took me so long to try this

Impressive Medical Grade TENS/EMS Unit!
I’ve owned the iSTIM EV-804 TENS/EMS 2-Channel Rechargeable Combo Machine Unit – Muscle Stimulator for just over 1 year now, and I couldn’t be happier. Although I’m not using it as often as I did when I bought while going through PT, I still use it from time to time, and I’m always impressed by the number of settings and its overall versatility. This TENS/EMS machine is easily up to par with what I used while going through physical therapy, and the number of settings and options built in sets it apart from some of the cheap junk TENS units you’ll find for $30.00 to $50.00 with only a handful of settings. If you want and need a pro-grade TENS/EMS unit, give the iSTIM EV-804 TENS/EMS 2 Channel a try. You won’t be sorry.

Long life
I purchased an iSTIM EV-804 TENS/EMS in 2021. Loved it worked really well. However, the output has decresed significancy. I tried new quality electrodes and the output is still not the same as it was when I purchased it.

Compact but powerful.
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.

Beginner’s large muscle injury EMS settings within this review.
This unit allows user controlled EMS settings (not just TENS, and not just “programs”), however the max width is 300μS (microseconds).Beginner EMS settings for hamstring area muscle injury: Mode S, Use 1 channel – 2 electrodes, Ramp 4 seconds, On 8 seconds, Off 24 seconds, 300μS, 50Hz, 15 minute session duration, 2 inches of skin visible between electrodes, electrodes placed on (along the length of) the injured spot. SEE THE NEXT SENTENCE.***The intensity level is controlled by a sensitive physical dial on top. FOR BEGINNERS the starting intensity must be less than 2 (out of 10). After feeling the sensation as too weak, raise the intensity only 0.25 (out of 10) at a time.***For example, if after feeling a contraction you feel that 1.5 is too weak, raise it to 1.75 and wait for the next contraction. Then if you want it stronger raise it to 2, then a contraction, then 2.25, and so on.If you raise it from 1.5 to 4 you may be VERY startled. I am not a therapist or physician.

highly recommend but the pads lose the gal quickly

Lo sto usando da subito appena consegnato e sto notando dei buoni miglioramenti. A fine mese dovrò comunque sottopormi a visita neurochirurgia per problemi di protusioni legati a sversamenti nella colonna vertebrale oltre a varie infiammazioni. Però il dolore si è notevolmente attenuato e probabilmente anche l’infiammazione.

I purchased this on the advice of my GP to help with my mobility and pain management. At my age, finding a safe and non-invasive treatment is crucial. I use the EMS mode daily to keep my leg muscles active and fight off weakness, while the TENS mode is absolutely brilliant for melting away my neck and shoulder tension. The machine feels very sturdy, and adjusting the intensity via the rotary dials is incredibly intuitive and safe. It’s a powerful little gadget that has genuinely improved my day-to-day comfort. Highly recommend it to any seniors struggling with similar aches!

Ich bin 52 Jahre alt, und in den letzten Jahren haben Rückenschmerzen und Muskelverspannungen zugenommen – besonders morgens oder nach dem Sport. Nach etwas Recherche bin ich auf das iStim EV-804 gestoßen und wollte es ausprobieren.Ich nutze am häufigsten den EMS-Modus zur Muskelentspannung und gelegentlich TENS zur Linderung von Rückenspannungen. Die Bedienung ist unkompliziert: Kabel anschließen, Pads aufkleben, Programm auswählen und loslegen. Die Intensität lässt sich genau anpassen.Obwohl das Gerät nur zwei Kanäle hat, reicht das für gezielte Anwendungen vollkommen aus. Die Elektrodenpads sind von guter Qualität und haften auch nach mehreren Anwendungen noch gut.Für Männer in meinem Alter, die regelmäßig mit Verspannungen oder leichten Schmerzen zu tun haben, ist dieses Gerät eine tolle, medikamentenfreie Alternative. Klare Empfehlung.

Mi Segundo TENS/EMS MáquinaComparado con el modelo antiguo, este no tiene esos diseños innecesarios (¡en serio, no necesito una mini pantalla que muestre modos de masaje que ni siquiera se sienten como los que seleccioné!).Por Qué Elegí Este JuguetitoPuedes ajustar la intensidad directamente girando una perilla, sin necesidad de botones arriba y abajo. Solo un giro, ¡y listo! La intensidad está ajustada, perfecto para los más perezosos como yo.Es la primera vez que uso un dispositivo que permite ajustar el ancho y la frecuencia, ¡me siento como un gurú de la tecnología!Comparación con el Dispositivo AnteriorEl dispositivo anterior solo permitía seleccionar modos de masaje y ajustar la intensidad con botones de subir y bajar, y tenías que detenerte para hacer ajustes.Después de cambiar el modo de masaje, tenías que presionar el botón de subir 20 o 30 veces para aumentar la intensidad, ¡una verdadera locura!Beneficios de los Programas IntegradosTENS P1-P12: Sin tiempo de uso establecido, se puede usar continuamente. TENS es para aliviar el dolor, así que no necesitas estar encendiéndolo y apagándolo todo el tiempo, ¡lo cual es fantástico!EMS P13-P24: Viene con un temporizador de 30 minutos, ya que EMS es para la estimulación muscular y no necesita ser usado por mucho tiempo. El dispositivo tiene diferentes tiempos establecidos para diferentes modos de corriente, ¡qué considerado!ResumenEstoy realmente feliz con este dispositivo; es simple, conveniente y potente, cumpliendo perfectamente con mis necesidades.El único inconveniente es que usa una batería de 9V. Aunque viene con una, necesitarás comprar más cuando se agote, lo cual es un poco fastidioso.Sin embargo, lo he estado usando a alta intensidad durante una semana seguida, y la batería aún no se ha debilitado, ¡qué alivio!
