This product works. I have extremely sensitive teeth so they are affected but I definitely see a difference in color just after one use. I will continue to use this product

Works very fast and very well. I was given the first time as part of a gift bag and i couldnt stop using my samples. I would definitely purchace many more veey soon

Tried this produce twice. Maybe my teeth are just sensitive, but they started to hurt so bad after using this product! I had to take them off and didnt finish the recommended time if keeping them on.

It whitens, but I’m fully aware of whitening teeth at home isn’t super safe. I use every so often and it works, but I try not use it too often. The price is kind of up there, but for quick fixes it’s ok.

Not sure exactly which product I get from Crest 3D white strips but all of their product are amazing and can always tell a difference within a couple of days! Always get compliments on how white my teeth are.

These whitening strips are great! They’re easy to put on and when you take them off, you can instantly see that they do their job. I had to stop using because I got braces, but the moment my braces come off I’m buying a new box!!

I’ve only ever used this whitening kit and it works really well. I can see a difference after one use. They re a little expensive, but i feel like all the whitening kits are

I use these for about a week every few months and have yet to have any issue. Most teeth whiteners leave your teeth really sensitive and these don’t, all while still whitening your teeth effectively.

I try to use these when I remember. However, for some reason when I have them on my teeth I lock my jaw and it ends up hurting my jaw very bad. They work great though and don’t make my teeth sensitive.

I like this product it takes such a long time for your teeth to whiten. You have to keep going and if you miss a time without applying it it would take longer for your teeth to whiten. But to be honest it is not my favorite teeth whitening product.
