AUVON Dual Channel TENS Unit Muscle Stimulator Machine with 20 Modes, 2 and 2x4 TENS Unit Electrode Pads

A remarkable device for my sciatica (lower back and thigh pain). From the first use, pain was greatly diminished. Very flexible and easy to use. A very powerful unit and one I absolutely recommend. I however have learned several lessons from 3 weeks of use. They are: • Read the manual fully before using. I only read enough to get started and had an accidental incident (described below). • Start with the lowest settings. I found an intensity of 3 or 4 (out of up to 20) to be what was most effective at reducing pain. Higher intensity settings were painful and did little more to reduce pain long-term. • For larger muscle groups, use larger 2”X4” pads. Smaller pads give a sharper stimulation and don’t impact the entire muscle group. The smaller 2”X2” pads are fine for smaller, thin muscle groups. • Pre-warm pads. Placing them on without doing so, feels like an ice pack being slapped onto your muscle, causing it to tense up. • Pads really adhere to the skin. With the initial use, they removed all leg hair that they were placed over. Removing them was quite uncomfortable (like being waxed). I’d recommend shaving any hairy area the pads will be placed on (the hair will be gone either way). • NEVER…I repeat NEVER connect a pad you’re wearing to the device without verifying the on/off switch is in the off position! I had one pad lead disconnect to the unit. I thought the unit had auto shut off. I didn’t verify it was in the off position and went to plug the lead back in. It was like being hit with a bolt of lightning or kicked by a mule! The capacitor must have built up a charge and let it all go into my leg when the connection was made. I surely will not make that mistake again! • In bed I found myself falling asleep after a few minutes of stimulation. Although it says not to sleep with the stim going, it was the only thing that allowed me to fall asleep. If used this way, shorten the timer to 10 minutes or less as the leads can disconnect with movement.

Im going to write this review about what it is and not what Id wish it was--because my wishes arent technologically valid. You put two sticky pads on your skin, navigate a clunky interface (no going back in your choices only forward) and you start shocking yourself. The electricity interrupts the pain messages. In a world of opioid addiction and during a Covid19 pandemic, this is unbelievably helpful. Because I cant just pop into a doctors office or get a back adjustment or massage or anything that involves being in close contact with people as I write this. I have two pads on now. I hurt my shoulder and Im sitting at my desk typing. Is it bliss? No. Getting the pads right can be bothersome. If youre in horrific pain, reaching around trying to place pads may simply be impossible. And the pads can activate your muscles. Relax, gym-a-phobes, you wont get swol. Youll just twitch slightly and involuntarily. Which is not as cool as it sounds and it doesnt sound cool. Also, you have a big no-no area around your middle torso. Because at high enough juice, youll feel it in your organs. Or at least I can. And having some outside electricity tickle your heart or lungs is a super scary feeling--to me. It didnt work on my knee. I couldnt really find a place I could put them and interrupt the pain. So things like wrist pain or hand pain might be equally tricky. All these sound like complaints. But theyre not, exactly. This thing is cheap, durable, rechargable and costs about as much as 3 big bottles of your favorite NSAID and its not a drug and doesnt have all those side effects. I had been amazingly skeptical of this. Seems like snake oil, right? But it works within the limitations of the system. If you got stomach cancer or eyeball surgery or had a sex change, I seriously doubt this will help you avoid pain. But for backs, arms, shoulders, legs, neck, etc. It works. I was gimping around yesterday because I hurt my back. I put on two pads and went bike riding--VERY SLOWLY. Ive done that numerous times since Ive gotten this. Another caveat, is this is only helping you ignore pain. The pain is still there. Its not reducing swelling/inflammation. Its not curing a damn thing. Its helping you cope. For muscle pulls/sprains and even stuff like slipped/bulging/generic-old-people disk issues, its great. Your body will eventually cure itself. Hopefully. But even long term pain, its either this or get hooked on drugs. And youre still getting shocked. Its not like a warm towel gently toweling you. Its zapping. So this product is about as good as the technology allows. I fully anticipate the 3rd 4th 80th generations of this stuff to be tiny diodes that arent sticky and clunky and can be placed with pinpoint accuracy like acupuncture needles. Just some shirt or snuggie or unitard where you say, ow, my right shoulder, and youre golden. But until that future day comes this is a great product. Just consider what your needs are, what you can and cant do, and all the stuff above.

Whatever you do dont skip on this item. When I say this is a must have for everyhome. It alleviates pain within minutes and makes you feel more relaxed.

This is easy to use. Has been super helpful for my boyfriend with his lower back pains. Havent used it above 3 yet. So far thats been great. Its small so you can take it just about anywhere with you.

It helps with my pain in my left left due to nerve pain. I use it on my back, legs its great to have especially fir back and nerve pains.

You need to use consistently. I have a really bad spine which causes the muscles around to spasm and lock. Which will leave me bedridden for about 2 weeks. The last time that happened, my daughter brought me this. It shortened my recovery time to 6 days! I used about 3-4 times a day

My husband has a lot of muscular back trouble- this one really helped him out in just a few uses!

I dont know if it helps with my back pain but it sure feels good when I use it.

Perfect, just what I needed. Small sleek design with multiple programs and dual output. My only comment is the amount of sticky goo that is on the pads. They say to use the tips of your fingers to place and remove the pads and you can hardly get the pad off your fingers. A suggestion would be an additional gel-free pull tab on each pad for ease of use.

I have painful hip arthritis and my PT suggested an IFC system which uses a different frequency than TENs - IFC/IFT. This unit (while listed for in IFC/IFT searchers) has no text in the description for either. It also looks like a really cheap product with very thin documentation and only graphics for what each mode. Given the number of these units on Amazon, I imagine a Chinese cottage industry producing these devices with similar features. I didnt notice any improvement when using it.
