Not Worth It, Just, Not Worth It,
This review is from: Crest 3d White 1-Hour Express Teeth Whitening Strips 4 Count (Health and Beauty)I received the box of express strips for Christmas. I put on a two hour strip. Afterward, my teeth looked no brighter...and I didn't expect them to because this is a one time deal. I would much rather suffer through the inconvenience of using multiple strips over the course of a few days than to do a one time quick session that doesn't do anything for me. I just can't believe everyone else on here that says they work great!
I recommend you buy the PROFESSIONAL EFFECTS strips instead of the express.
