I used this for a month before my family pictures and my teeth were amazing.

WORKS, BUT NOT TOO CONVENIENT.
The strips do work over the course of a week or so, but they do ooze a bit in your mouth and it's a little hard to talk. Compared to the cost of a professional whitening, the Crest is worth some of the akwardness.
