Red Light Therapy Device for Pain Relief & Skin Rejuvenation - Portable LED Light Therapy for Home Use, Muscle Recovery, Anti-Aging, and Joint Pain Relief - Perfect for Home Spa, Fitness Recovery, and Skincare Routine

I have had this unit several months. The only thing I disliked about this item was the light on the wall charger. The instruction indicate when the light should come on and go off, etc. but my unit is very touchy. However, it has never failed to charge. I find just moving the battery in the charging unit usually makes the charging start and I leave it overnight. Morning, unit is charged. For pain relief, I find it has helped my joints in my hands and feet. It took several treatment of only 2 minutes or so before I felt so relief. The more I have used the unit, the better the results.I am very happy with this purchase.
