I use this every once in a while it is easy to use and works great. Wouldnt use it for everyday use and can not replace basic teeth stuff.

I received a few samples of the crest whitestrips and was very satisfied with the results. We have since purchased a full size box and we are very pleased with the results.

I didn't believe that they would work. But, after only two weeks, my teeth were noticeable whiter. love these things!

Does absolutely whiten teeth, but the strips don't really whiten the back teeth.

Despite hearing that whitening your teeth with these kind of strips is not good for your enamel, I thought I would try it at least once! And oh boy, I was so pleased with them! I used the 7-day pack, twice a day and my teeth got at least 3 shades lighter! Granted, they weren't too horrible to begin with seeing as I'm not a smoker or pop drinker, but nonetheless, the results were great! :)

I have got to say this product works great! Fast, easy and convenient way to whiten and brighten teeth. Seven days is all you need and in as little as 3 days, you will already start to notice the difference in color. The only thing I would say that is a little uncomfortable is the sensitivity of my teeth I experienced after about 4-5 days of using the product, but it was only temporary and sensodyne helped tremendously!

I first got into this when I was on holiday in New York and ive been addicted ever since. I couldnt believe how white my teeth looked after a few days. Was an immediate improvement! Great product and affordable too. The one problem I had was that it made my teeth a bit sensitive and I had to stop puttin the strip on one of my teeth! But i carried on using it and was so pleased with the end result!!
