This is the handheld massager that delivers 3,350 soothing pulses per minute to relieve sore muscles. The percussive massager loosens tight knots, improves circulation to sore muscles, and delivers a deep, penetrating massage that hastens healing. The device has four interchangeable heads—one simulating the feel of four fingertips, a thumb-sized node for targeting larger muscles in the back or shoulder, a fingertip-sized node for pinpointing small areas, and a flat head for wide, deep-muscle massage. The unit’s 8'-long cord and 1 1/4'-long handle allow you to treat hard-to-reach areas in the middle of the back or legs. The massager has different speed settings for customizing the intensity of treatments. Plugs into AC. 16" L x 10 3/4" W x 6 1/2" D. (3 lbs.)
