These strips are absolutely amazing. I know a lot of people have sensitive teeth when it comes to whitening strips but these really do the trick. They work the best compared to anything else I have tried.

I saw a wonderful difference in my teeth after a week! so I stopped and now I am just saving them for when it gets closer to holidays for the perfect smile!(:

I've used these for years and I always get amazing results. They do not leave your gums irritated or sensitive. In just 30 minutes there's a huge difference. These are the best whitening strips! 10/10

These actually really hurt my teeth but I think that they did help make my teeth whiter. I don't like how they have to stay on for so long but if they work I will do anything to make my teeth more white

Good product. As long as you keep using them for a few weeks, the strips really do remove tea and coffee stains on teeth, and get them several shades whiter.

crest whitening strips are one of the best at home whiteners. They may seem pricey when purchasing at the store but they are worth it. I always see results.

I've used these and also recommended them to my patients. You will see significant results within 1-3 times of using them. I now only have to use them every once in a while, usually for special occasions. =)

I've used this product for a long time, I really like it but it doesn't keep my teeth white after a couple of days. Compared to other products, these have been the best over the counter white strips.

it makes ur teeth really white but it also makes them very sensitive so it hurts when i drink cold water and stuff, don't know if i would buy again for that reason but it does the job

If you use these white strips as recommended your teeth will become about five shades lighter. I don't see anything to improve this product, it is not a dental tray product. Your teeth may get a little sensitive so be careful.
