This is my second review of Platinum Theraphy Lights, I can not say enough about this system BIO Max 900 series. I am no way associate with any medical profession, however my experience has been great. I've had outstanding results with: Getting a restful nights sleep, I had a severe itching and rash problem aquired over 30 years ago while vacationing on a tropical island, and no over the counter or prescription medication would suffice. I've had excellent results with lower back pain, the results of using the Platinum Red light system are too many to list here. The key word in using red light theraphy is "Consistency", I do, and have recommended Red Light Theraphy to my family and friends.
