The strips work great!
Size: 40 Count (Pack of 1)
It's a great product that works. I left the strips on for 2 hours. And my teeth were so white, I decided not to use the light. I drink 3-4 cups of strong coffee everyday, and they are still really white (after one application over two weeks ago). My gums were a little sensitive after 2 hours, but that only lasted a few hours after usage. Just be aware if you leave on more than 60 minutes. Then brush and rinse really good. I use their "brilliance" tooth paste as well.

DOOOO IT (see before & after pics)
Size: 40 Count (Pack of 1), Size: 40 Count (Pack of 1)
My dentist actually recommended this in contrast to the products offered in office! So I had to try. I was especially interested in a whitening system that would not sacrifice effectiveness for gum sensitivity. Not only could I see instant improvement, but I had no gum irritation whatsoever, not even next day. So that's the two big things that exceeded expectation. A few drawbacks though - (1) Instructions were unclear as to how long to leave the light on, & I didn't realize until after mixed Internet recommendations & testing it out blindly that it automatically times out after a few minutes; (2) the product unfortunately outlasts the light's battery life, so I had to find a $16 replacement LED on Ebay, & (3) the adhesive will strip your dental work fyi. Not cool, but still overall beneficial as a whitener & hundreds cheaper than true, professional whitening. BTW this before and after were taken within a month of each other.

Amazing transformation!!
Size: 40 Count (Pack of 1), Size: 40 Count (Pack of 1)
I hardly ever write reviews, but this product has transformed my life. And imonly on the forth day. After the first day it removed so much of my yellow stains. I can't even think about how white my teeth will be when I finish. I called my dentist to see how much it would be to whiten my teeth and she said $500. Are you kidding me? So I ended up trying these white strips instead. I'm so happy with the results after only a few days!! The first picture is the start, then after using the strips 1 time, then after using the strips 3 times. I had to come and post a review immediately. The pictures speak for themselves. And not to mention that I usually have sensitive teeth. So far my teeth don't hurt while using. I will definitely use this product every year. Thanks Crest!!
