EV-804 TENS/EMS 2 Channel Combo Machine Unit - Muscle Stimulator + Back Pain Relief and Pain Management- 7 modes (Including 8 Pieces Electrodes Pads)

I think TENS blocks pain signals, while EMS stimulates muscles. This compact device comes with everything you need, including 8 reusable pads, 2 wires, and 1 9V batteries. This compact unit is ready to use right out of the box with the batteries. Nice one

The media could not be loaded. I've been using TENS EMS devices for years. My old one was thinner and had a touchscreen. I once put it in my back pocket during a trip, and the screen went black. So this time, I got a button-operated device without a touchscreen. I love its color and timer, but you can't set the time in the built-in modes from P1 to P24. The power and effectiveness are great, though the buttons can be a bit unresponsive.PerformanceThis device is fantastic for pain relief. I bought it for my osteoarthritis and use it on my knees before long walks. It's hard to believe such a small machine can output so much power through four electrodes. The belt clip is handy. The black design looks cool and doesn't feel cheap. Unlike other brands, I need extra breathable tape to secure it, but it works really well.Battery LifeThe battery life is impressive. I've used it for two months, half an hour to an hour each time, and the battery is still strong. The downside is it's not rechargeable. It comes with a 9V battery, but you'll need to buy replacements when it runs out.

After few months of sleepless nights due to painful shoulder ( basketball's fault) my husband had his 1st proper night sleep.Machine was easy to set up, stickers keeps well in place, clear instructions with pictures provided. Loving the adjustable option on the top of the machine so it's at easy reach.Need a bit of time to work with settings first time, but automatic function does it all.Small and lightweight so doesn't get it your way while walking.

I got the Stim EV-804 TENS,EMS machine for my friend who needed a portable, battery-operated device. It's small but powerful, perfect for on the go use. We started with the TENS function for his back pain and saw relief within the first week. Now, we use the muscle stimulator function, which has been incredibly helpful.We chose this certified therapeutic grade device over cheaper options, and it has exceeded our expectations. The only downside is that more channels would be useful for larger pain areas, and a USB charging option would be convenient. We worked around this with rechargeable batteries. Overall, I highly recommend the stimulator for anyone with back pain.

Great Product and easy to use,

Value for money level, speed setting, battery life is great

At the beginning, I wasn't sure I should buy it. But I was recommended by my friends who are also badminton players, we use it sometimes for sport and to replax. It's really very useful and a product which you can recommend to people around you. It's practical to use if you read how to use carefully, it helps you to relax. It's not complicated to use though the beginning was a bit confusing to use it to connect the wires and so on. but then it's very convenient to go through. thank you for the fast delivery.

Mon épouse souffre du dos et les kiné utilisent ces appareils. Nous avons testé cet appareil et nous ne sommes absolument pas déçu. Nous ne l'avons pas depuis très longtemps mais déjà elle apprécie le fonctionnement. Peu être que la prise en mains peu être améliorée mais en tant qu'utilisation, il fait très bien le job et soulage grandement les douleurs.

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!

Acquistato principalmente per usufruire della funzionalità EMS per la stimolazione muscolare elettrica che con due canali, due modalità e ventiquattro programmi preimpostati permette di 'far lavorare' gran parte dei muscoli del corpo. Comodo e poco ingombrante con elettrodi di qualità, lo utilizzo giornalmente lavorando in smartworking. Ho apprezzato anche la funzionalità TENS che presenta cinque modalità ed ho avuto modo di appurare la netta riduzione del fastidio alla schiena. Dopo un mese circa di utilizzo posso quindi affermare di aver acquistato un prodotto valido.

I received the TENS/EMS about one week ago. I noticed both the center connector pins on the box were bent and there would have been no way to plug in the leads. Trying to do so would have only damaged the connectors more. I used the point of a letter opener and bent the pins back to a center position the best I could. I was then able to plug in the leads. It was hard the first time but the pins centered from lining up with the plug and it became easier to plug and unplug. I started using it but a couple of days later I decided I should let the seller know about this even though it’s working. Pins that have been bent are more susceptible to bending or breaking. I sent Everyway4all an email on Sunday and they responded immediately. They sent me a new unit Priority mail the following day with an envelope and self address paid label to return the one I had. That’s GREAT Customer Service!Now for the unit itself. This is my third and also my best TENS/EMS unit. It does exactly what they say it will do and it does it well. I bought this one because you can dial in the intensity rather than pushing an up or down button 20 or 30 times to select your intensity. This is also the first one I’ve had that let you adjust frequency width and rate while you are using it. My most recent one required me to stop the unit, make the adjustment, start the unit and push the up button 20 or 30 times if I just wanted to make one small change. I’m really glad I bought 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!
