i have tried these but they haven’t worked too well. i see a small difference but not as much as i want for my teeth!

this is definitely worth the money I have gotten so many compliments on my teeth just wish they were a little bit more affordable

It’s a noticeable difference. I think it works well and is worth the price. I think you can find cheaper options but they don’t work as well.

These are perfect for pretty white teeth upkeep . Definitely will have your teeth sensitive afterwards.

These make my teeth shine! I wear these every once in a while when I need a pick me up and they really do the trick! 

I feel nervous about these I put them on and u don’t want to keep the on too long because they give my teeth a tingly feeling

...the lower strips are too short. It would have been nice if they were as long as the upper strips.

Love these will continue to purchase more they give a noticeable difference and won’t break the bank

I have never felt more confident in my smile than I do today! Thanks Crest for the awesome product that produces results and has an affordable price!

Works really well for whitening teeth in a short period of time. It does make your teeth a little sensitive afterwards though.
