Pure hype and marketing BS
The intensity of light this thing puts out is about 100 times lower than the red light level that has been shown to be clinically effective. The manufacturer touts the 6-month money-back guarantee, and then when you read the instructions that come with the thing, they basically say if you use this thing 20-minutes per day every day, then *after* sic months of use, you will start to see the "real" benefits. Hogwash.
