Oh how we really love this neck massager! The whole family! Husband and I work a ton in front of the computer and our neck always gets so stiff and sore. We just love putting this massager on our neck while watching TV in the night. It did feel a little weird first time though. Just be careful not to put it on high first if you don’t know how strong you can take because it may create involuntary muscle spasm while using it. It’s such a weird feeling! Lol! Father had shoulder surgery and he loves it too. I’m thinking about getting one for him as Christmas gift.
Purchased for a stiff neck awaiting medical review. Works well once the instructions are carefully understood. The heat feature is nice. The different modes are difficult to discern which once is operating but still the gadget is great!
For the price it’s not bad. It has good power. And seems to do the job. The beeper when you change speeds is loud and annoying. Other than that seems to be ok.
Good product, everything is fine. I like the feeling when turn massager on, relaxing. Arrived in 10days that is super fast! Recommended!
Constantly plagued by neck muscle pain. Hate to be tied to a heating pad and electric outlet. This is the best solution to comfort and maneuverability. Fifteen minutes of this therapy and my neck pain diminished to near zero and full mobility to turn my head was restored. Love this product - it was definitely worth the money. Highly recommend.
I though I received a broken product. However, I just misused it. First of all, I need to gently wet my neck area before putting on the massager. Then, push the start button. I feel comfortable to use this neck massager, and it feels like electricity flows through my neck, relaxing my neck muscles. This neck massager has a U-shaped design, which can fit almost everyone’s neck. And come with a remote that can control 15 different power levels and 3 different massage models. Most important, it comes with a heating mode. I like it white color. I like it light. I like it comes with soft cushion. I like it easy to use. I like it can relief my neck pain. The overall quality is good. I really like it.
The massager is good! I liked it! immediately turned on a strong mode because such procedures did constantly in the hospital, After 15 min, the signal paged and turned off!!!! I liked everything very much. I recommend to buy a massager and store as it pleases both the goods and delivery. The remote is very convenient! Thank you so much!!!!
Love everything about this product! Helps to relax my muscles in my neck and shoulders.
This little gadget took a little getting used to at first but after my second use, it felt wonderful. Fits comfortably around my neck and the heating function feels amazing. Simple operation and the instructions were easy to read. The beep sound is loud so I can be sure that I can hear the modes changing or the unit turning off. The auto shut off after 15 minutes was a nice touch as well. Small and low profile makes this easy to take with me when I am traveling.
AMAZING! This neck massager is very good quality and does a great job relaxing the neck and shoulders. It warms up very quickly and is easy to control the strength of the pulses. I HIGHLY recommend the store who did a great job communicating and did a great job with the packaging. Try it out, it's definitely worth every penny :)
Saw on Instagram an add about this product, bought one, has been delivered faster than thought and it works great. Even my mother who has cervical pain it helped her to relieve her pain. Recommend store and product.
Fast shipping and product is as advertised. Just like a tens unit but without the cords and sticky pads. Really helps my neck pain!
The product looks exactely like the description and the pictures! Very nice soft touch. Works perfectly fine.
It's very nice packed and quality looks very good. I tried it. It works also good.
Came very quickly, in two weeks. Everything works. Heats and massage current discharge. Well sits on the neck. Pleasant sensations, helps to relax the neck. Thank you!
