I tried this product a couple of months ago. I must admit I was looking for a blinding white smile. Now my teeth aren't yellow to begin with, but being a woman who can't start her morning without a cup of coffee I thought it couldn't hurt to add a touch of brightness to my smile.

This product is better then the old whitestrips in the fact that it bonds to your teeth so they aren't sliding all around your mouth for 30 minutes. Also I didn't experience any sensitivity to my teeth with these.

My only problem with these strips are the fact that I was expecting more whitening power. While my teeth are pretty white, i was hoping for whiter.

I've used this product in the past and was pleasantly surprised with the results. My teeth did get whiter over a few times of using the strips. It is a simple product to use.

I've been using these for 3 days now and I can notice that my teeth are definitely brighter. I had some sensitivity the first two days but it wasn't unbearable. They definitely stick in place unlike the other crest whitestrips.

I got several free samples of this product and i loved it. i used it the first time i got it and i was so happy with it that i bought more. i would so recommend this to anyone.

I got a few of these as samples and am super impressed. I have tried the other Crest whitestrips and hated them mainly due to the fact that they were so slimy and sipped all over the place in your mouth. These hold true to their name and really do have an 'advanced seal". They stick really well to your teeth and don't slip all over and you don't get left with that disgusting taste in your mouth. They feel a bit odd on your teeth because they are thicker than other kinds, but much easier to use and seem to get your teeth whiter. My teeth were not very discoloured, but I did notice them to be a bit whiter/brighter.
