I find that strips work well for a short time.

I bought these expecting great things as I love the Crest 3D White products generally.
I found it difficult to keep the strips attached. I ended up taking them off within a few minutes. I still have the remainder of the box in my bathroom. Probably never to be used again.

Amazing product! You can tell just after a few uses that your teeth are whiter. I'm not a fan of the 'gucky' feeling in your mouth. It is an expensive product.

My teeth were noticeably whiter after my first use. I found them easy to use and fairly convenient. I found it left my teeth a little sensitive after use. I would recommend this product.

The whitening strips whiten your teeth as promised! My teeth looked noticeably whiter after trying just one whitestrip. I find them a little on the pricey side, but they do perform! I did notice some minor tooth sensitivity after using them, but that only lasted for 1 day. I would recommend trying these, they work!

Loyal user of crest white strip the never let me down! And yes they work!

works as well as professional bleaching for much less money

Tried these for a few weeks and no visible change

Best whitening strips I have used to date. I have not used the extreme whitening or the 2 hour express but it does the job for me. Holds well to teeth and not sloppy. The only thing I would change is the size for the lower teeth - they could be a bit longer.

It was the first time I used whitening strips on my teeth because so many people were raving about them! So far, I used it twice and I got to admit that it's not easy to not swallow the product! Hopefully the effects are guaranteed as the box indicates! Keep you posted!
