Very, very painful and quit working entirely within minutes
I got to use this once for probably 3 minutes and then it died forever. During the time it worked, it wasn't even warm and it felt like it was trying to knead it's way into the base of my skull. It felt nice on the shoulders on the muscle but the moment it hit the bone, ouch!!! I HATE this thing. Honestly I'm happy it died, I may have been tempted to try it again....
