MediCrystal Infrared Heating Negative Ion Amethyst Tourmaline belt. Not working- for parts or repair. In good clean used condition. Controller is not working properly. Could possibly be repaired or replaced. Item comes as pictured and is sold as is. I have used this mat with a regular heating pad underneath to heat it up- so it is still usable. Controller does work sometimes but most of the time it won't heat the mat.
