I absolutely love this product I don't have to spend the money on a professional whitening because this product works so well!!! I love only having to whiten for a few days and then not again for several months!!!!

I loved using these strips! They are so convent to use. I saw results the next day. Even if you forget to whiten one day your teeth are not prone to stains.

I found them on sale 5 years ago and I am addicted to them. I figured out that I can reuse them when I need to save money. I get compliments all the time.

[This review was collected as part of a promotion.] Absolutely love these white strips! I immediately notice a big difference just after one singular use. I have sensitive gums and they do not seem to irritate me.

I have used this product many times and it works extremely well. I always notice a difference after the first treatment. I have had to cut back lately because they have become so expensive. I am a single parent so other priorities come first.

I had very yellow stained teeth, now that I used this product it did not leave them pearly white like I wanted, but my friends have noticed that they are whiter. I will buy a new box in hope that it will get them the kind of white I want them to be!

These whitestrips were wonderful. The best product that crest has to offer. However, I dont know if I would use them too often as they seemed very strong. Made my teeth pearly white and thats saying a lot as I drink coffee all day every day!

The 3D white toothpaste is the best purchase I've made. I can't use any other toothpaste, it leaves your teeth so shiny and clean. You really do see results within a week!

First time I tried them my teeth were yellow from coffee and tea drinking you could really tell the difference got many compliments on how white and bright my teeth were

I have been using for 2 weeks and haven't noticed any change. A couple packs of my strips wouldn't even stick to my teeth. Very disappointing. I'm guessing I received an old product.
