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.

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.

YEOWCH! Be careful of the neck contact pads!
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!!! 🫣😱

Different but satisfying electric pulse massager
I didn't quite know what to expect from a "massager" that delivers relief through electric pulse technology, but after a week of using this product, I can confidently say I'm happy to have it in my arsenal of massage therapy tools. If you're expecting a traditional push/rub massage, this doesn't deliver that. It sends electric pulses of varying strength (which you can increase/decrease using the intensity buttons) and patterns (which you control using the "mode" button), which make your neck muscles rapidly tighten and relax. It's a really unique sensation and I enjoy it! I could, however, see how some may not find this too appealing. If you're looking for a more modern and unique way to relax, this may just be for you. Other positive aspects are the heat function, the remote control (which conveniently can be stuck onto the massager due to a magnetic clip), and the long battery life. Overall, I'm satisfied!
