These work great! My only complaint is that they make my gums a little sensitive so I have to take a break from them. Which is fine because they work after a few applications.

Noticed a huge differences right away.i am a smoker and Cafine drinker. This product has made my smile much more amusing to look at.i feel beautiful!!!!

They definitely work! I have pretty sensitive teeth so I don't whiten often. But when I do, these are my go to. They don't leave my teeth achy like other whitening treatments do.

Honestly the best I've used so far….works in one or two times. If you have a sensitive teeth I would recommend using half the time just see if it will hurt your teeth.

These Crest 3D white luxe professional effects whitening strips are the best! When you drink coffee and red wine, you need these babies lol These work really well, even my dentist has commented on how white my teeth are!

Works very well, kind of expensive and sometimes hurts my teeth if they're sensitive but the effects are worth it, they leave your teeth very very white

Along with Crest whitening toothpaste, I use these whitening strips a couple times a week. they leave my teeth showing a simple layer of a brighter white each time that I use them. They are a little on the higher side, but they are SO WORTH IT!!!

VERY EXPENSIVE. But my boyfriends had extras and let me try them. I'm absolutely in love. It's just very hard to keep my teeth white, so this helps a lot

Crest Whitestrips are the best over the counter whitening agents available, hands down. I don't know why there are so many different variations (professional, luxe, etc.), they all seem to work the same, just with different price tags.

Great product . You can tell the difference. Helps make your smile look bright if you do it consistently.its effective and the price isn't bad . I'm also a repetitive user ! I'm overall satisfied with this product. Works good if used correctly .
