It is a good product but you need to keep on using it to keep your teeth white

These are amazing & made a huge difference in the color of my teeth.

I can wear red lipstick without worrying about my teeth looking yellow!

These are by far the best whitening strips on the market!

This product has brightened my smile!! This product truely works!

I love the way it removed my coffee stains and left my teeth white. I give this 5 stars

I have used other products crest is by far the best

Have tried the others, Professional white strips are the best

This products not work at all. I’ve using them like a month and I don’t see any chance.

The product worked extremely well. It made my teeth brighter.
