TENDLITE PRO Red Light Therapy Device - Clinical Grade LED Light Therapy for Joint & Muscle Pain Relief - High Power Home Treatment for Back, Neck, Shoulder Pain - Perfect for Athletes & Chronic Pain Sufferers

I'm new to LLLT (lower level light therapy) and am astonished that this product is so easy-to-use because of its small size, portability and quality.It doesn't emit heat as it's not supposed to because it's not a food warming light seen in restaurants, nor is it a microwave to cook food nor a cellphone tower. It is low on the light spectrum.As a beauty aid, it does minimize my facial wrinkles although this isn't why I bought it. This is a marvelous bonus.I suffer from a rare muscular disease that causes extreme muscle weakness. I shine this product on my throat to aid my speaking, as well as hands, feet and brain.LLLT is helping ease my symptoms. I also bought, from AMAZON, a floor model whole body red light therapy device to use.The special glasses fit beautifully over my eye glasses.Watching YouTube videos by Chiropractic Neurologists, physical therapists,etc who use these products is very important and easy. LLLT should only be used for a few minutes per session.I suggest you do your homework. YOUTUBE videos are especially helpful to me.Red light therapy has been used for decades so the science is well researched.This is a great little product to help muscles.
