This product does work and does not cause as much sensitivity as other products. It's a good value and for most people will do exactly what they expect it to.

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.

Noticed an improvement in whitening after 2 applications. I have sensitive teeth and gums so I did have to space out applications more than what was suggested

I used Crest 3D White Whitestrips a few months ago. I was so amazed to see how white my teeth got gradually! I have tried other products but they didn't work. You can't beat this product!

I love these white strips I’ve always used the crest white strips sense when I can remember. The only thing with them is I noticed that my teeth tend to get a lot more sensitive after using them.

I ended up buying a professional kit as these tasted so awful I couldn’t deal. I haven’t given it a full chance and for the price I went with a reusable tray.

I think this is a great product for teeth whitening. While it’s on the pricier side, it is painless and convenient to use. The only con is that you have to be consistent with them or else it starts losing its effect.

I have tried many at home teeth whitening remedies. This by far has been the easiest to use and the most effective. Twice a year I will buy a pack and use them to keep a nice white smile all year. Love them

I was skeptical if these would work or not, but they do. If you keep using them you will see results. Takes a while but it does work. I’ve tried other strips just to compare but it gets a bit messy. These ones don’t have that problem.

I did notice a difference in my teeth after using this product. The strips itself I think have a weird taste to them but it’s worth it for the results !
