I was amazed at the difference that these white strips made! And the amount of time that the whiteness has lasted is great! Be sure to use them for the full 30 days to get the full effect. They do make your teeth very sensitive so be aware.

These are perfect if you are trying to whiten your teeth. The tray alternatives have not worked for me but the strip do. The only problem is the my teeth are very sensitive the next day. I would buy again because I got amazing results.

Very expensive but they do work. My teeth get very sensitive so sometimes I have to take them off earlier than usual but my results are still great . I don't do it often since it's not good for the teeth

These are ok. They won't create lasting effects or get rid of any yellowing from over the years but they will make teeth appear a little whiter. They taste bad though.

Good product, but I just can't bring myself to use them as often as suggested. I may use them 2-3days in a row every few months or so as a whitening boost.

I like Crest Whitestrips and have seen a difference in the whiteness and brightness of my smile. I don't love the hoppy residue left over on my teeth after using the product, but I brush my teeth afterward anyway, so it's not that bad.

So far, these are my favorite ways to whiten my teeth. Price is decent and they are effective (way better than gel in my opinion) but they still taste awful and can be difficult to apply to the proper areas on your teeth.

I love these and use them once a mouth for a week by far the best decision! Everyone needs to try these! They're by far my favorite I buy them a lot! Will never switch they're well worth the price! I definitely recommend!

these are surprisingly good! they're a little uncomfortable when you first wear them, but even after one use you can see that your teeth are slightly more white. with regular use, i feel like you'd be able to see a big difference in your teeth.

I've been using this product for years! I'm so impressed with the results and love the shiny bright white teeth it gives me! Definitely affordable and I recommend all the way!
