Great purchase!

I suffered a soft tissue injury as a result of a car accident and often found my neck and upper shoulders to flare up. My physio therapist recommended that I rotate hot and cold. This was a great buy. It has three settings and will turn off automatically after a certain period of time. It has a magnetic clasp on the front which keeps the heating pad in place! Several of my coworkers have purchased these for when they're at their desks! Its amazing!
