These things really work!
I am so happy with how white my teeth look! I can't tell you how many people have commented on them--people who didn't even know I was using the strips!
Just 2 complaints--1) the strips are not long enough so they only whiten the very front of your smile. i have been creative and am cutting the "extra" part of the strip to put on the sides
2) damn, they make your teeth sensitive! so sensitive that being out in the cold air hurts them! but i have sensitive teeth normally (can't ever use ice in a drink!) so this just makes it worse
I'm convinced!
