NUSmile Teeth whitening

Ok, I am a true PJ (product junkie if you are unaware). I went into the mall and sa this the other day. Wish I had taken better pics of before. I saw the change like right away. I was shocked. They rated me a 3.5 and after 1....that's a change of 6 shades. WOW! I have thought of trying this in the dental office many times, but just couldn't see myself paying 800 bucks for it. I watched the movie and thought long and hard an did it. I keep looking at my teeth.
