Goodbye Winter Pains - My medical condition makes cold weather an absolute nightmare for my hands and joints, and I've honestly tried at least a dozen products to help me with this pain, but this one is by far the best. CozyCharge took care of the problem and adequately warms my hands without causing any irritation. It's small and gets so warm - you have three heat settings, but I've never needed to use the highest one. No more red, swollen fingers, thanks to CozyCharge, and I couldn't ask for more.
