HATE! They did their job of course BUT I fell asleep with mine on and I was in more pain than I'd been in my entire life! They're obviously TOO strong.

I struggle with my smile after having braces, I feel like my teeth have never been as white as before. These have immensely helped with my self confidence and I find myself smiling more than before

These Whitestrips work, however they have made my teeth extremely sensitive. If “beauty is pain” is your thing then go for it but the discomfort I encountered isn't worth it for me.

Makes my bottom teeth super sensitive to the touch. Didn't notice much of a difference. I am hoping to try one that is in electronic device sometime soon

After just one use my smile is soo white and bright. It doesn't slip while using which is very useful. It does though make my teeth a little sensitive.

I like using these to get my teeth white. I can't use them all the time because I have a few broken teeth and when I put these strips on, it makes my nerve endings hurt. I usually use it about twice a year. 

I only use this before special events but usually about 2 weeks before I will start this whitening treatment and I'm always super impressed by the results!

These strips are my favorite. I m 51 years old and these get my teeth as white as I want them. I will continue the use these. They are easy and the sensitivity is not bad.

These are the best teeth whitening strips! The work so well and do not leave my teeth feeling achey or sensitive after using them. That is so important to me when using a white strip. I will continue to use these for a brighter, whiter smile!

After trying these, I will never try anything else! You really only need one box and after that, you just have to maintain with good brushing and oral hygiene! I get compliments on my teeth all the time and it's 100% due to these strips.
