iStim 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'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. Performance This 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 Life The 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.

iSTIM EV-804 Digital TENS EMS Combo Stimulator combines the benefits of both TENS and EMS in one device, making it a versatile and effective option for pain relief and muscle stimulation.

Great value for money—impressive speed settings and excellent battery life.

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

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.

Such a amazing device. It nabbed the place we're electrode pads are attached. I used it also on my belly on ESM setting. I could feel and see my muscle moving. Very powerful. I use TRNS it for my shoulder and sciatica pain. I love the numbness it gives after session. 2 in 1 such a great idea

Really nice and effective electrotherapy machine. I am a physiotherapist and i used it for my patients, really good reviews from them as well. Definitely order if you are thinking to. Modes are really effective and more then 5 modes you can use with just a one battery.
