These whitened my teeth without hurting them! Two to three uses and I noticed shade difference. These are pretty expensive though. But you can buy in bulk from bulk stores.

I seriously only had to use the a couple times to see dramatic results! They work so good and haven't made my teeth sensitive. I use these around 1 or 2 every two weeks just to keep my teeth white and from staining from coffee and food.

Ive used all types of different white strips and I have found that these are more effective than the others. Makes my teeth super white and is sensitive on my teeth.

Honestly I don't really like this product at all. I've seen others have success but for me it only whitens some of my teeth giving them more of a stained look

The best white strips I've tried. You have to leave them on for a few minutes each, top and bottom. They whiten very well. And unlike any others I've tried they don't hurt my teeth at all.

these whitening strips work really well. if used correctly they make your teeth really white. however, wearing them for an extended period of time is honestly super uncomfortable because the product foams up and tastes bad

They do work! I don't like too white which looks kinda fake, this is just making my teeth at the color I like! Don't use it too long tough. You need to follow that direction.

I love This combo package deal . The light works perfectly . I whiten my teeth for about 30 minutes then when done I rub the extra whitening gel all over my teeth before rinsing out for better results .

Love the convenience of having these in my home. I use them sporadically to keep my teeth looking pearly white all the time. Easy to use! And bright white!

i love this product because it's helped improve my smile everyday it giving such a beautiful white look from the crest whitening strips! definitely get them if you don't it, it's a need
