I highly recommend Bianca for her exceptional customer service. She went out of her way to mail me a brochure with all the information about red light therapy and its uses. I have used the mat for 14 days now and I can honestly say it has made a huge difference. I had a serious back injury - compact disk fracture and 2 herniated disks .The red light therapy has given me so much pain relief while regenerating muscle tissue and t promotes healing and inflammation. Great service and awesome product. Thank you Bianca. PS- also great for hair loss and skin regeneration .
