I used this leading up to a friends wedding and I truly saw a big difference. As someone who consumes products regularly that stain teeth I thought this product worked really well

Best over the counter whitening strips I've been using these for years before they raised the price..that's the one thing that really sucks is they are expensive now.

Weirdly, this didn't work as well for me as the regular Crest white strips. I didn't really notice a difference when I used it. It didn't hurt my teeth like the original strips, but it didn't give the same results either.

I do believe this works over time however it strips the enamel from your teeth and leaving it on for the whole time hurts your teeth. I do recommend if you use it once wait a couple weeks to do another

Got a great BOGO deal on this from the website. It truly whitens. It makes your teeth sensitive so I would recommend getting a sensodyne or a similar toothpaste to help with that.

These whitening strips really do work! It almost gets addicting to see how white your teeth can get, so you have to be careful! But they really do give you such white and beautiful teeth.

These are hands down the best whitening strips I have ever used! I can notice a difference after just one use. Don't leave on more than recommend time or else you can have a sting in your tooth (if they're sensitive).

Oh wooooow this is a great product. It really helps to get your teeth whiter than white. I used this product before I went to the dentist and they where asking me how did I get my teeth so white. It's not time consuming.

These are a good to use to maintain a pretty white smile. I do this set twice a year and it allows me to have pretty white teeth along with regular check ups and brushing at least 2 times a day.

If you want white teeth buy these! They work pretty quickly and you can pretty much see instant results. They don't leave you with sensitive teeth after and they have a nice grip.
