I am a chef with constant strain on my neck and upper shoulders. I’ve also got a right shoulder desperately needing surgery to decompress the muscles, and repair bone spurs. I’ve cooooonstantly got big knots in my traps and neck. This massager is everything that’s advertised. I use the straps to add or remove pressure, plus I can position it to areas of my neck that need some work. It actually feels like someone is rubbing with their knuckles. I get chills every time I use it! The heat is an added bonus as well. Given that my condition can only be fixed with surgery, this massager definitely helps work out what my body will allow.
