My sister uses these strips religiously and her teeth are amazingly white (She gets compliments ALL the time, and before these strips, her teeth were more yellow than mine!) Of course, after seeing her results, I too decided to give these a try.

After using these NOT as directed, I did see some pretty fantastic results (I only used once a day, for 30 minutes, 3 days a week). They pretty convenient to use as it only take 30 minutes and you can use them any time of day you'd like.

I like how easy these are to put on and continue with my morning routine. They are so comfortable to wear that I sometimes forget I have them on at all. They are virtually unnoticeable so sometimes I even go to the store wearing them.

What I do not like about these strips, however, is that, even though they claim not to cause teeth sensitivity, I find that my teeth hurt like crazy after wearing them for more than a couple days in a row. (I have NOT noticed any long-term sensitivity issues, however.) Honestly though, after trying many other whitestrips, I have found that these work the best and cause the least amount of pain.

I DEFINITELY recommend these to anyone who needs/wants to get great results quickly!

I'm a big fan of white strips. Any white strips. The easier to use the better. When I heard Crest was getting a new line of whitening products out I knew I would have to try them.

The instructions were fairly easy to follow. They directed me which strips went on the upper teeth and which went on the lower.

The strips went on smoothly. Sometimes I find with other kits and/or brands that the strips are too thin, making them harder to put on. But the Crest strips went on smoothly and stuck to the teeth that they were supposed to with out bending or getting stuck on my fingers. They felt gooey on my teeth at first but as they began to do their job they felt more firmly stuck to my teeth.

These strips take 30 minutes to do their job but since they fit so comfortably I barley noticed that they were there. I went about my day as I normally would have. One of the good things about these strips were that there was no real taste to them. It was easy to forget that they were there.

After the 30 minutes I went to remove the strips and found some problems doing this. The strips were still bound tightly to my teeth. Since my 30 minutes were up I yanked the strips off regardless of whether they wanted to come off or not. They came off in a couple of pulls, not very willingly, but they did come off. I'm not sure if such pulling was good for my teeth.

However I was happy with the results of the white strips. They did exactly what they promised, make my teeth whiter in 30 minutes.
