The whitening strips are very well developed. It is one of the only whitening products that have successfully whitened my teeth without mistake. They leave you looking professionally whitened.

Extremely easy to use! I've used them for about 3 years now and I wouldn't change a thing! Once you apply them, they are so comfortable I wear them in the shower and doing my makeup! The results are great! Highly recommend!

HANDS DOWN THE BEST PRODUCT EVER!!! I can't get enough of these! I use them all the time. I love the how easy they are to use, love the effects, and it truly makes my teeth look amazing! I tell everyone to buy these!!

This is definitely a go to product. It really helps getting you teeth white. The only down flaw of this product is it not very good for people with sensitive teeth. Mine are sensitive sometimes when I use this product!

I have used the original white strips for years and love them. I do not like these hard thick strips. They are uncomfortable and don't mold around teeth as well.

Crest White Strips are worth the price. I have gotten my teeth professionally whitened in the past but honestly the strips do just as much. My teeth are pretty sensitive to things but they feel just fine when I wear these. 

Works great. I took away a star because I had braces and have to careful with my gums— I can't let these rest on my gums. However that being said they work really well at whitening teeth and don't make your mouth water too much.

I honestly didn't like this strips. They fell off my teeth while I was using them & the nasty gel stuff tasted bad! I saw a slight difference in the whiteness of my teeth but not much.

This product is super good at whitening teeth. The strips themselves don't move around a lot and there is not really an aftertaste when you take them off.

I use these to whiten my teeth at home. I do notice a difference as my teeth appear whiter. Are they going to give you professional in office results? No. But not all of have time nor can we afford to go in an office to get our teeth whitened!
