Helped cure my persistent neck pain but...be careful
This thing rubs hard! which was great for loosening some persistent muscle tension & spasms in my neck. However, it literally rubbed the skin right off of me in my mid-back, while wearing a t-shirt. Kind of a rug/brush-burn thing. I wanted to write a glowing review since it helped with my neck, but I sent one to my sister and now I need to call and warn her to be cautious.
