These are great for a quick refresh and for a complete do over. They take yellow, stained teeth to pearly white in about a week or so. I use them every other day for about 10 minutes and my teeth have never looked better.

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.

Great when you need a quick whitening before a big event or date. Gets your teeth a couple shades whiter in a matter of 25 minutes. I use these on rare occasions so I don't buy regularly but for someone who needs then, would recommend.

Overall I really do like these they're super simple to add to your daily routine and leave your teeth with an extra bit of whiteness that being said I do find them a little expensive for what they offer

It took me a long time to bite the bullet and buy Whitestrips, but dang, they really do work. I don't have tooth sensitivity so I don't know if they might bother people, but they don't bother me. Definitely worth it ahead of a special event.

I was hesitant to try this because I'd heard bad things about other kinds of whitening brands however this was a great experience for me! Very easy to do and was very happy with my newly whitened teeth.

I love these. My teeth look amazing, no sensitivity afterwards which I was apprehensive about. I have been using the strips for two years and I will continue to do so.

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.

My dentist always asks me how my teeth are so white and it is because of this. I use them randomly throughout the year instead of a short treatment to decrease the sensitive of my teeth with the product!

It iis simple, before appling the strip to your teeth, make sure they have been dried off with a tissue or towel then apply, The strips stick much better and that is not talked about at all,
