These work miracles!! Very great product! I was embarrassed about my smile before. Now I love to smile!

I love these white strips. THEY WORK GREAT!rather than paying thousands to get your teeth whitened.these do the job!

I love these! Some people stated it burned there teeth but it never did that to me! In fact, I've noticed a difference after using them 2-3 times!

Love this! I have been using these for about 3 months now and never the less I can say my smile has never been brighter!

I'm a smoker and a coffe drinker and my teeth stay white with this awesome product! Thank you crest .

Haven't used this for a while, but when I did I liked it and thought it worked well for an over the counter product.

I like it - i thought it made my teeth whiter. I liked that my teeth felt smooth and polished afterwards, like i just came from the dentist.

I hate these. They always fall off of my teeth. They're not effective at all. I don't recommend purchasing.

Use these once a month or whenever I feel I need a bit of whitening. As a coffee and tea drinker. I need a whitener and this is the one I like.

Do not waste your money! The Crest 3D whitening strips do not work whatsoever. I've tried them twice but I wouldn't try it again.
