These work so good it's not funny! Every now and then I will put one in just to stay on top of it and I love it. However, if you have sensitive teeth this is not for you unless you space out your whitening sessions.

I really loved the Crest 3D products. I could tell a difference in the color of my teeth in just one use. I would recommend this product to anyone. Great Product and worth every penny!

Really whitens my teeth and it doesn't taste that bad. They aren't uncomfortable to use either but if your teeth are sensitive I would be careful because sometimes it can hurt

Crest 3D whites has flipped my world upside down. There is absolutely no need to go to the dentist and pay for expensive treatments when you have this product! The change is instant and is inexpensive! I am a satisfied customer!

The whitening strips always make my teeth highly sensitive, but they do their job. My teeth get noticeably whiter! Just don't eat anything cold after!

I love Creat Whitestrips. i am a very impatient person and i never feel like they have to be on for too long. the results i have had are amazing for the price of this product and i use them religiously.

I love the strip for a fast result I can put them on when I'm getting ready they really help with special events when I want my teeth extra white I love them they do what they claim.

These definitely work! You can see results after one use and people always tell me that my teeth are so white. The only downside is that it can make your teeth sensitive. Other than that, I highly recommend.

These strips are my favorite. I m 51 years old and these get my teeth as white as I want them. I will continue the use these. They are easy and the sensitivity is not bad.

I love them for making my teeth very white. if you have sensitive teeth however, these may not be the ones for you. for how well they work, they are super cheap. such a great deal
