I have used other Crest Professional Whitening strips with great results. These are a big dissapointment. I like the stickiing power. But I'n not seeing much whitening from them.

They do not work at all it is a lying false advertising applying them daily even used 2 boxes didn't even whiten teeth by the slightest waste of time and money

I love how white and great my teeth look after using them. Best of all is all the compliments and boost of self confidence I get knowing how white my teeth look!

For the past 3 months I've been using this toothpaste. its absolutely the best. my teeth look and feel healthy, And to mention the whiteness of my teeth. every time I smile my teeth shine bright like a diamond!!

I am a coffee and tea drinker and after several years, this has ruined the whiteness of my teeth. I think the effects of this product was well worth the price.

I really love all Crest 3D white products, but these professional effects strips are my favorite! 30 minutes a day for three weeks and I have beautifully white teeth!

I got at least 5 shades whiter, an hour may seem like a long time but I just do chores and homework, cooking etc and set a timer. Bam! White teeth. Barely any sensitivity, if at all.

[This review was collected as part of a promotion.] These really work to help whiten teeth and stay whiter. Easy to apply and didn’t make my teeth sensitive like others I’ve tried. Good whitening option.

[This review was collected as part of a promotion.] I love it. It's easy to use. The taste is pleasant, the packaging is practical, and the price is good. I see results in a week. My teeth are whiter; it's real and effective.
