Review: Minor Flaws but Overall a Great TENS EMS Device - 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.
Review: TENS and EMS in one device - 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.

## Features

- ✨TENS: "Transcutaneous Electrical Nerve Stimulation"- a 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, the Tens unit could effectively block the pain signal in people’s brains.
- ✨EMS: “Electrical Muscle Stimulation” is an internationally accepted 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.
- ✨iSTIM EV-804: Digital TENS EMS combo stimulator comes with 2 channels, 5 TENS modes 2 EMS modes and 12Preset programs, sending comfortable impulses through the skin that stimulate the nerve fibers in the treatment area.
