Really like this for anyone who needs white teeth fast. It take off any stains on teeth from coffee or wine or anything else. Your teeth will look so much better!

I have this product and I really do think it brightens my teeth over time. I recommend it if your trying to get whiter teeth. Make sure to try their whitening strips !

I like these strips because they stay put and actually whiten like they should. My teeth are pretty sensitive so I can't use them often, but a few times between teeth cleanings is good.

These white strips work well after a few uses you can definitely see a difference! My teeth tend to be sensitive so I need to space out uses based on how they feel after I use these strips but overall good results

This product definitely works very well. After I finished the box I noticed my teeth were alot whiter and I got a ton of compliments on my smile!no have repurchased this several times over the years

Great product and have noticed a big difference over time when using once a month or once a week however do not get the strip on your gums! Your teeth will ache and if you have sensitivity already maybe look to a whitening toothpaste only instead.

It's good but it falls off your teeth alot which is wicked annoying it does make your teeth whiter! Just the whole process and the time it takes is very inconvenient

great whitening strips. they help maintian my whiteness without stripping my teeth. I don't leave them on the whole time suggested though because my teeth do get sensitive.

Whenever I use them, I notice a difference after one use. Sometimes I experience a bit of tooth sensitivity but then I limit my use. But I love this product and use it frequently.

For a product that you can get without going to the dentist, crest is great. Very effective depending on how much you put it on. But if you leave it on to long or use it too much it does make my teeth sensitive
