Red Light Device for Body Joint and Muscle, Infrared Light Machine Hand Held Redlight Wand for Home Use(4x808nm +12X650nm)-White

For us, we like to use red light therapy when we pull a muscle, have tendon aches, or recovering from a surgery. For our dogs, this is fantastic to use when they are older, pull a muscle, or recovering from surgery.This device is so easy to use. Charge it up, click to turn on, click to start. Can't get any easier.Device is light enough to hold. I like the feel of the handle.When I am using, I am constantly moving this in slow motions around the affected area.Always wear the safety glasses! Even animals should have eye protection or have their heads covered.so for this is helping with a neck strain that I've been suffering with for 2 weeks now. I'm starting to feel some relief after a few times of using it.These red light therapy devices are fantastic to have in the home.
