I am a college student and a weight lifter. My hands are being used all the time, whether it be to type on a keyboard, write essays on pen and paper, or lifting weights at the gym. Because of this, my hands are always tense and feel very stiff. I constantly crack my fingers to relieve tension and sometimes they are in pain. Using this product was the best feeling my hand has ever felt. This device sooths the muscles in the hand and wrist super well, relieving tension and loosening up the muscle.See full review
