This is the hand massager that uses air compression and heat to help ease pain in the hands and fingers. Ideal for those suffering from carpal tunnel syndrome, arthritis, or fatigued hands, it massages away knots while its optional heat setting promotes blood circulation to help ease soreness. Unlike similar hand massagers, this unit targets not only the palm, but individually treats fingers. After a hand is inserted into the device’s soft polyester interior, a push of a button begins one of three modes, one of three intensities, and one of three heat settings. Works on either hand. Charges via USB.
