  • 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, 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 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. Then when the pulse ceases, the muscle relaxes and the cycle starts over again.
  •  iStim EV-805: Rechargeable Digital TENS EMS combo unit stimulator comes with 4 channels, 5 TENS modes, 3 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! 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.

High-quality machine, long-lasting electrode pads

I don’t usually write reviews, but this device absolutely deserves one. I purchased the iSTIM EV-805 and from unboxing to daily use, the entire experience has exceeded my expectations.
The product arrived well-packaged and in perfect condition. When I opened the box, I was impressed by how complete everything was—multiple electrode pads, lead wires. It truly feels like a professional-grade device right out of the box, and you don’t need to purchase any additional accessories to get started.

This unit offers a wide range of modes and intensity levels, allowing you to fully customize your treatment depending on the area and level of pain. The electrical stimulation feels smooth and consistent strong enough to be effective, yet comfortable without any sharp or unpleasant sensations.
I mainly use it for back pain relief, and after just 15–30 minutes per session, I can feel my muscles relax and the pain noticeably decrease. It has quickly become part of my daily routine and is now an essential tool I rely on.

Honestly, I was a bit skeptical at first, but after a few uses, I was convinced. The strength and adjustability make it easy to target specific pain points, and the relief is very noticeable. It’s especially helpful for anyone who sits for long hours or deals with chronic back pain.
One of the biggest surprises was the quality of the pads. The package includes plenty of them, and they are very sticky and durable. Compared to cheaper alternatives, these pads last much longer, making this device more cost-effective over time.

I love this unit it surpasses all other Tens/Ems machines, the dual, 4 channels, is perfect, in assisting with pain management and muscle development.
Im glad I purchased this amazing unit.

The learning curve takes a bit of effort, but it is worth the time. After a few days of familiarizing myself with the unit I took the unit with me to an appoitment with my physical therapist who walked me though some of the tens patterns he uses in his practice to treat my whiplash and lower back pain. This instruction helped me to focus on those setting that provide the pain relief specific to treating my injury.

This is isn't a set and forget unit. I selected it because it is most simiar to the ones that my physical therapist and chiropractor uses.

I've owned lower powered, single channel, pre-programed units in the past which did perform well but were limited by their single site application and limited programming options. Add to that battery replacent was a constant expense where the Ev-805 is rechargible and the savings on battery's alone justifies the price of the unit.
