Perfect for neck nerve and muscle relaxation
This is my first TENS device. Some first impressions and thoughts after several uses. 1). The build quality is top-notch. It's well designed, and the body and the electrode pads seem to be good materials. 2). Compact and comfortable to wear. I used it in different settings - sitting in front of the computer, standing while preparing food, and moving around in the house. 3). The tingling feeling at first takes some getting used to. After that, I feel noticeable relief in my stiff neck. The TENS therapy seems to work by improving the circulation while stimulating the nerve and the muscles. 4). I'm still trying out the different modes, heat levels, and intensities. I wish there's small display on the remote to show simple mode selections and intensity level, so I can remember the best settings. 5). It's not a deep-tissue kneading massager. It uses nerve and muscle stimulation rather than physical pressure. It's less invasive but may not provide the direct and immediate hands-on feels. For me, I plan to use this TENS unit regularly like 5-10 minutes break after working long hours at my desk. Because it's portable and so easy to use. I can bring it with me to office or when I travel. I will use a Shiatsu massager only when my neck is really stiff and need deep muscle manipulation. Overall, it's a perfect TENS device for its purpose, easy to use, compact and portable, and effective for neck nerve and muscle relief.

Next generation of neck pain relief from Comfier!
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.

If you like pain, you'll love this
Awesome if you like pain! I made the mistake of waiting until after my allotted time to return this item and now I'm stuck with it. It does absolutely nothing as far as massaging. It feels like tiny needles digging into your neck. It uses electrodes to zap the skin, not pleasant at all! I guess I'll save it and gift it to someone i hate.

Edit - Wasn't the biggest fan at first but it does ok now
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.

Worth the cost and effort to use for my sore neck muscles.
Nice fit for an adult male. Heating feels good and gets fairly warm - all the heat I want. TENS stimulation is gentle and subtle, with many levels and seems to work nicely. Smaller unit than I thought it would be but fits and works well. Nice warranty and company support - it appears. Hopefully it will last. Well packaged and charging cable is included. Directions require some figuring out with language issues to some degree, but it is fairly easy to figure it all out. Not as expensive as many similar units. I am a happy camper.

Okay but needs improvement
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.

Very, very nice device!
I had surgery on my neck years ago and have damaged areas, so I am getting quite a bit of use out of this. It feels like a TENS device with really good settings but is much easier to use. First let me go over some of the specs. It’s charged via USB, has controls both via a remote and on the side of the device. It has a number of modes. It has a heat function. It is lightweight and of substantial construction. It is easy to use because the contacts are built into the device and it slips on like a half-collar. If you don’t use heat the charge lasts a LONG time. With heat you’ll have about 50 minutes. It charges in a few hours. It has settings that are called various things, like shiatsu, tapping and cupping, but I just did trial and error and found one that has a combination that works well for me. It can be set so it’s pretty intense, so start low. I very much enjoy this kind of TENS stimulation as it relaxes my neck. I keep it by my computer and use it daily. It is small and easy to use and there is no complicated set-up to deal with. That makes it much more accessible than other devices where I have to deal with cords, wires or sticky contacts. This means I use it often. Anything big and complicated, well, it tends to sit and collect dust. This is the opposite. This feels high-quality and is comfortable in my neck. The only thing I would ask for is an on/off on the remote. You can use the remote for everything else, but not on/off. Also, make sure the contacts are in good “contact” with your neck or you’ll get what feels like static electricity. If you feel that just turn off and reposition. I’m very happy with this item.

Well Thought Out Product
I have a different EMS/TEMS stimulator with pads but I never use it because it is such a hassle with the cables and sticky pads. This is where the COMFIER neck massager shines. This unit is so easy and quick to use. I absolutely love it and I use it frequently when I am at my office job. This device is very well thought out. It is very flexible for maximum comfort and functionality. The remote can be attached to the massaging device via a strong magnet (remote battery is a CR2032). The heating functionality works great and you can feel it warming up within 1 second. Some of the massaging settings I don't like so much but you can change it and I do have a favorite one that I really like, and it remembers the last setting it was on. Built quality is really good and COMFIER offers a 3 year warranty if you register your product within 60 days. You don’t get a warranty like this for most products you buy.
