As the largest and most complex joint in the body, the knee is a common area for problems. Massage therapy can be beneficial for flushing away the fluids that lead to inflammation and swelling. Using techniques similar to those used by professional therapists, dual air bags inside this advanced, rechargeable massager gently inflate and deflate, replicating soothing compression massage. Simply secure over your knee, adjust the touch-fastening for a custom fit, and choose one of 3 massage levels on the easy-to-read LED touch screen. Three optional FIR far infrared modes penetrate deep into tissue, whilst 3 variable vibration modes disrupt pain transmissions without drugs. Ideal for stiffness caused by exercise, injury or age. 10-minute timer. Auto shutdown after 2 minutes with no operation. USB charger included. H14.5 x W24.5 x D17cm.
