The iComfort Heating and Vibrating Electrical Massager proves that good things really do come in small packages. Fabulously fun and pleasantly powerful it uses high-frequency vibration and flap massage functions to help release aching and fatigued muscles. The tapping movement by the two rotary heads activate blood circulation and improve cell oxygenation. This deep tissue massager is handheld and has an ergonomic design that makes it easy to target your sore spots even between the shoulder blades.
