The whitening strips are very well developed. It is one of the only whitening products that have successfully whitened my teeth without mistake. They leave you looking professionally whitened.

They stick on your teeth well compared to other brands. My teeth were so much whiter after completing all the strips. The only downside is I had mild sensitivity.

When you look in the mirror you will feel like a whole new person. You will feel more than confident to smile in public and you WILL NOT have to try to hide your teeth ever again.

The whitening strips always make my teeth highly sensitive, but they do their job. My teeth get noticeably whiter! Just don't eat anything cold after!

I've tried a lot of whiting strips but this one I can say actually worked and didn't hurt my teeth! I have had a problem with strips hurting my teeth really bad but this was amazing!!

I love these strips! I've never had a bad experience with them and everyone I know who uses them loves them too. Be cautious that they do make your teeth sensitive and it is a 7 day “treatment”.

Easy to use and fast results. Whiter teeth and removal of coffee or wine stains within a few tries. No teeth sensitivity if you follow the instructions. Professional whitening results.

I have sensitive teeth and these strips didn't irritate my enamel when using them. Saw results relatively quickly. Would purchase again and Recommend them

The crest stripes are a little on the pricey side , but they have made such a huge difference in my teeth and make them probably 2 shades whiter ! I use these maybe twice a month and I am obsessed. I drink coffee and my teeth are still super white!

I love these! I have fairly white teeth to begin with, so I mostly put one of these on for special events or date nights. They work well and are easy to use.
