It does look pretty cool... but I saw the review for that on the news the other day and they had two of their interns try it. Their conclusion was that it did not work and both subjects said that they would never buy it... Their before and afters were the same. Crest whitestrips work wonders

I don't use them, my dad and boyfriend do and they love them (I can't cause I have fake teeth) Veneers work wonders too

but not on your wallet!
