teeth whitening product that explicitly says to use it for 1 hour and then use the blue light afterward.

"This product is a waste of money. It doesn't whiten any better than any other type of their whitestrip line. I used it consistently for the full 10 days with negligible effect. I cut the whitening time down to 40 minutes due to schedule and then did the blue light. Would NOT recommend!"

What is wrong with people?
