Crest whitening strips are honestly the best and more cheaper way of getting your teeth whitened really fast. I like how you can find them at any store. There could be more strips for the amount that people paying for.

I use these all the time. They're super easy, throw them on before the shower and by the time you're done showering, they can come off! They don't leave any residue behind and visible changes after just a few uses.

I have been whitening my teeth on and off for 20 hrs now. I started with crest white strips I. High school, used a lot of different things, even professional whitening and Crest white strips does the job the best.

i like this product a lot and it always does the job but it does make ur teeth very fragile at least for me . i would recommend this but if your teeth aren't very healthy i wouldn't recommend you use this product.

This product does really work but it also leaves you with a super sensitive teeth. The results happen very quickly but only if you could deal with the pain of the after affects. I think that they should work on that

At first i honestly didn't see an outcome, nor should you go into using a new product thinking that it well show a big effect two seconds after! But after I consistently used it! It was great and I love the over come effect!!

They stay on my teeth well which is nice because my teeth aren't perfectly straight. They do however cause sensitivity so I only use it once a week to try and keep my teeth from getting discolored.

love the 1 hour strips I can really tell a difference in my teeth. It can feel a bit weird on the teeth so if you are sensitive just keep that in mind

Defintielt can see a difference in my teeth but I also notice them being a lot more sensitive after using for a few days in a row. I would definitely spread them out to avoid that and use a toothpaste like sensodyne if you have sensitive teeth.

It works amazing! However, if you have sensitive teeth, DO NOT USE! Just after 2 times, I used it and my teeth were in so much pain, but they were so white! I had to stop. I recommend this product to people who don't have sensitive teeth!
