these are GREAT! i was already seeing big differences after like one use! my teeth are very sensitive and i can’t use them often without my teeth hurting, but i use them occasionally and my teeth don’t hurt and they’re looking a lot whiter already!

I personally love these teeth whitening strips! They work wonderfully and they don’t make my teeth too sensitive which I love. I have experienced sensitive teeth with whitening strips before, but these ones aren’t bad.

I like these Whitestrips from Crest! It does what it promises and I don’t think my teeth get overly sensitive afterwards. I wouldn’t use it for consecutive days though. I would definitely buy it again.

I was surprised at how white my teeth were after using this product to the end. The strips sick to my teeth fine and don’t move around once they’re on. They’re a little hard to take off but I think that’s normal. They work fantastically!

The strips are amazing and in expensive , it's easy and convienant , I love getting complimented on how white and bright my teeth look .. It's a great product you won't be disappointed

In only one use, I truly felt that my teeth were way whiter than they had started out being. The effect does wear off however, so it’s not meant to be only one use. Overall, satisfied!

My first time getting my teeth whitened was so painful, my gum line was chemically burned. With these whitestrips there is minor sensitivity but overall it's great even only at day 5/14!

I’ve been using these in preparation for my wedding, and they are AMAZING! My teeth have never been so white. I’ve been getting so many compliments and I always say that this product is the way to go. I would HIGHLY recommend.

I LOVE my crest whitening strips! I get compliments all the time on how white my teeth are! I’ve tried other products and nothing ever compares! I will always be a crest fan!

I used this for the full 20 days and I didn't see any results. I spent money that I don't really have right now on it, and really wanted it to work...I ofcourse lost my receipt so I am out of that money...Oh well :(
