Instant relief
Even though I gave this only a 4 star rating I would definitely recommend it to family and friends. It works great and after suffering with a stiff neck for about a year I got relief after just one session. The combination of heat and vibration works wonders. The reason I rated it 4 stars and not 5 stars has nothing to do with product performance but has to do with user instructions. There isn't any. There's different settings for the vibrations and for the heat. You have to figure them out for yourself because there aren't any mention of them in the little booklet they provide. All in all this is well worth the money and as I stated I recommend this for anyone with stiff neck muscles.
Rating: 4 stars
