Amazing. I love love love the way I feel when I have a beautiful white and bright smile. This is a staple part of my beauty routine. Worth the money.

Hate that Crest tests on animals but these really work and people comment on my white teeth all the time. Up your game Crest- stop the cruelty!

Although I like how easy these are to use, I honestly didn’t notice as much of a difference as I had hoped for or expected.

So easy to use and works wonders in my teeth. It is really affordable and i love it! I think if i would change something it would be the after taste

I use my Whitner 1once every 3 weeks and I absolutely love them my teeth look so nice and white only one use. It did meet my expectation and beyond.

my teeth were visibly whiter after only a short amount of time. i used these before prom and had great results.

Definitely the best teeth whitener I’ve used. pretty pricey but so worth it. Every other brand I’ve used has been nothing compared to crest

This product is a lot of money but however it does work. The dentist recommended me to use them since I have a white spot on my front tooth.

I really enjoyed this product and could see results after a few uses! It’s simple to use and helped me get white teeth.

Sadly I haven’t seen any change. I’m in the 5th. week and haven’t missed a day. I’d appreciate some guidance from the company.MM11
