COMFIER Transcutaneous Electrical Nerve Stimulator

On my a few of last visits to a physical therapist, he used a TENS (Transcutaneous Electrical Nerve Stimulator) to relieve the pain on my lower back. TENS a non-invasive pain relief mechanism that uses low-voltage electrical current delivered through the skin to stimulate nerves to release endorphin and reduce pain feeling. Basically, the physical therapist put a device that includes multiple electrodes on my back near the pain source through which the electrical impulses. My lower back feels tingling of different degree which is because of the electric current is transmitted to my nerve through the skin. My back feels substantially better after a few treatments, and I was very impressed by the pain reducing effect by TENS, after each run of 15-20 min.Last week on a whim I searched in Amazon to see if there are TENS massagers available. I came across this Comfier TENS which is designed to reduce the pain on the neck. Today almost everyone who works before a computer has neck pain. I decided to pull the trigger and give it a shot.After having used this device for 3 days my conclusion is that this TENS from Comfier has exceeded my expectation. The Comfier TENS functions appear to have 5-6 modes including tapping, cupping, scraping, shiatsu, acupuncture, etc., the intensify of each can be adjusted through tapping the “+” or “-“ button on the remote. My sweetest intensity is about 10 (when the device is on, the intensity is the lowest, so by 10 I mean I click “+” 10 times), and at such an intensity my skin is tingling but not very painful. The real beauty about TENS is that my neck feels so good one hour after one run, probably because endorphin releases in a delayed manner after use.It appears that when the TENS is on, the two electrodes are also heating, which adds to extra benefit of improving blood circulation on the neck.It also appears that the two tips of device also have heating feature, which can be run simultaneously or separately from the nerve stimulation function.

EDIT ---- I've had the device a couple more weeks and have a better understanding how to use the item. I've increased my review from 3 - 4 stars since I've found a setting that better satisfies my needs of the device. (The strength in particular) The heat in general is suffice (still would like it better) but with the adjustment of settings one can utilize with the electrostatic functionality, it has helped me numerous times if I had a stiff neck.The item arrived overnight per Prime shipping. The item was securely packaged as one would expect. The item self seems to be produced per normal standards. The remote is attached to the side of the device via a magnet. Speaking of the remote, I'm not sure why one would use it since on the opposite side of the device are another set of buttons to change the settings and power the device. A short USB Type C cable was provided for charging which worked fine. My problem with the device is the lack of heat. It does provide heat but it isn't a heating pad type of heat so I'm unsure if it'd help enough when there are strained neck muscles etc. The electrostatic feature also seems to work but I am not familiar enough with that type of therapy to know the benefits or detriments. I've had the device for approximately a couple weeks and to me, it probably is overpriced for MSRP lists.

I was not sure what to expect but soon realized that this product offered pain relief at a nominal price.I sometimes wake up to a “kink” in my neck and I used this product while working, walking and driving in a road trip.The “tingling needle prick” sensation takes a little getting used to but that quickly subdues after the initial “jolt”. You set the intensity and start low and work up your tolerance. This product definitely delivers

My wife wanted me to try this device---early Papa's Day gift---and I quickly discovered that it was like a tens unit, without the sticky pads.My neck issue is not tired, sore muscles, it is neurological in nature (severe spinal stenosis that compresses my spinal cord, and impinges nerve roots in my right neck & shoulder), so this device is useless to alleviate my pain...Also, I have a fairly thick neck (the young lady in the pic on the device box has the neck of a gazelle, so, for her, it must be comfortable to use), and the side pads were compressing my carotids on both sides, making me feel woozy...when I tried to gently pull the device side pads apart to relieve the pressure, I inadvertently caused one of the contact pads to lose contact on the back of my neck---and it felt like I got tasered on my neck, the shock was so bad! And the same thing happened to my wife when she put it on---she shrieked when the pad lost contact on her neck!!! 😳⚡SO...to say that this device is not for me/us is a mega-understatement...anyone looking to purchase any device like this one (or others), be advised that it is for MUSCULAR neck pain only---and for Pete's sake, do NOT adjust it on yer neck when the device is ON!!! Turn it OFF before you touch it!!! 🫣😱

Wow, this device is incredible! I personally had no idea a device like this could exist, and it was a joy to find it. I work a computer desk job, and hold so much tension in my neck and shoulders. I foam roll and lacrosse ball out the neck/shoulders daily, but there's only so much I can do. The e-stim with gentle heat in this device really help the muscles relax their tension in a novel way that provides both pain relief and a reduction in my daily headaches. I highly recommend this product!

I like this unit somewhat but it needs some improvement. First what I like. It is lightweight and easy to travel with. I like the remote as well. You can control the intensity from the remote. What I do not like is that you have to hold it flat against your neck to get the best treatment. Otherwise it will sting from not making good contact. It helps with my muscle tension in my neck somewhat but I prefer my Stim unit since I can move the placement and I do not need to hold it.
