I was so excited to buy my Crest 3D whtie strips. I did exactly as the instructions said and I was so disappointed. So all that money down the drain. I'm happy for those that received good results but I think Crest should stand behind the product when it does not meet the expectations of it's customers, namely, me. :-(

Love using these, can totally see a difference even after one use. I took a star off cause they can be pretty expensive and after wearing my gums are always a little sensitive. Taste isn't pleasant. Despite those couple things I still use them all the time.

The whitening strips are the best thing ever. They don't taste very good though so I put my retainer over it and it does the trick. I put them on while I'm doing my makeup and by the time I'm done my teeth are instantly whiter. Just make sure to brush your teeth before and after.

I noticed a difference within one week. I love the rapid pace of the whitening. I did notice that my teeth became more sensitive but I still really enjoy these. People ask me how my teeth are so white. Crest 3D White Luxe Professional Effects Whitestrips Teeth Whitening Kit

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!

I am obsessed with all of crest 3D products especially these strips! My teeth were yellow before and I have the pics to prove it. I discovered these strips and stayed consistent with the toothpaste and the mouthwash as well and I could not be happier with the results. I get complimented on my teeth all the time and my confidence is at an all time high!

These strips are AMAZING! They stick to your teeth and do not fall off when you talk, like other brands. It only takes thirty minutes and I could tell the difference in just the first use! The first time that I bought them, I used them every other day for about two weeks. My teeth have stayed very white. I drink coffee everyday, so naturally they will get a surface stain from that, but with one use of these white strips, my teeth are perfectly white again! I would recommend these to anyone looking for a great whitening product. They are a bit pricey, but definitely worth every penny!

I bought these because so many people swear by them but unfortunately I didn't get the results I was hoping for. They made my teeth incredibly sensitive so I couldn't use them every day which may be the reason I didn't get good results, but they were disappointing on the whitening aspect. I will be looking to try a different product next time.

Super easy to use and worthwhile. I could probably have better results if I used this regularly. Instead I use them as a monthly touch up instead of the daily use they recommend. At my last dentist visit, they all oohed and ahhed over how white my teeth are! No problems with sensitivity.

These work super well and are very easy to use. I like to put my clear retainers over my teeth when these are on to keep them in place even better. The only issue is that my teeth are kind of sensitive and after using these it makes them more sensitive. But, crest also makes sensitive relief strips that I can use after those two relieve my sensitivity.
