I love these. They are very effective at whitening your teeth. They are easy to use at home. So convenient!

I got a sample of it but it had no taste to it plus it did not stay properly on it did white my teeth a little bit no I don't recommend

I use the 1 hour express version and it’s amazing. I always like to have them on hand because it honestly is pretty noticable immédiately!!!

Probably were working, but they made my teeth hurt extremely bad for hours after a short use. Not worth the pain.

I enjoy using white strips to maintain the shade of my smile. The crest strips are easy to use and simple to put on and pull off.

Great product just wish it was a bit cheaper. Have to keep up with it if not your teeth will stain again. Gets the job done if used correctly

I think these work quite well. However, the result seem to only be noticeable in the first couple of weeks.

These work. The results only last so long but its a good while. Going to buy more soon, has been like 2 years since I last did one

This is an awesome product! Works very quickly and your teeth look great for months!!! Would highly recommend!

Definitely makes my teeth whiter. Sometimes it can make them a bit sensitive but that goes away. Recommend using frequently and not as a one time
