Review (5/5): Love this whitening product!
I have been using this product on and off for a long-time now. I've received so many compliments on how white my teeth look. I really recommend the CLASSIC Crest White Strips. I have used the Premium in the past (which are more expensive), and there was no noticeable difference (in whitening, or speed of effectiveness). They are so easy to use, no muss no fuss- leave on 30 minutes, you're done. I put them on before going out for the evening, or in the morning before getting ready. There's 56 strips too, so they seem like they last forever!
Great product, easy to use, and actually works. Can't ask for much better in an affordable whitening strip.
