[This review was collected as part of a promotion.] From the first strip it worked. Packaging is great nice and small. Price is great because it is super affordable. I noticed that the strip needs to be placed on teeth and not the gums. However, it didn't make my gums that uncomfortable. It worked and beats from going to pay 100s of dollars.

Crest 3D White Luxe Professional Effects Whitestrips Teeth Whitening Kit worked good and got my teeth white.  The product works and it worth getting and using. the price is little expensive. I give this product 5 stars because it worth it. So go out and get some Crest  Whitestrips. You will not be dissatisfied

This really does help whiten your teeth but you got to have patience to wear these for half an hour every day! I find that whenever I use white strips I salivate more and have to occasionally spit out (they say it's safe to swallow but I feel like it tastes like chemicals).

I've bought these a couple times. They work pretty well. You see results after about 4 uses like it says on the packaging. Sometimes they are a little hard to stick on your teeth so I dey mine with a clean towel before putting the strips on. If I use them too frequently my teeth get sensitive but that happens with all teeth whitening methods.

This product is absolutely amazing!! The strips stay put on my teeth well and are easy to apply! After using these strips just once my teeth already looked whiter! This kit is a very cost effective way to get quality teeth whitening in the comfort of your own home!

My 16 year old daughter wanted to whiten her teeth, and my dentist recommended Crest Whitestrips. I really wish I could post the "before, during and after" pictures we took. Amazing results, we can not believe the difference in just 7 days! I would definitely recommend trying these.

These really do the job. My one down side to this product is that it's so gross tasting. I mean duh, no bleach should taste good. “ beauty is pain” and well disgust, but it does it's job and that's all we want. It takes a few times before getting the shade you want.

This is the OG right here, I don't think it gets much better for this (unless you were to buy something professional). I have used this product for a few years now. It has become an "old reliable." I recommend that anyone try this product if they are experimenting with at-home teeth whitening for the first time!

[This review was collected as part of a promotion.] My fault for not taking a before photo, but my teeth have never been whiter! They are so easy to use, and super convenient. It’s a quick and easy solution rather than going to have them professionally done. I will be buying these in the future!

These are easy to take on and off! I love that they're disposable so I dont have to worry about keeping up with trays or gel. They have a kind of bad taste when the whitening solution is working but they definitely give you a whiter, cleaner looking smile!
