No slip whitening strips from the 3D white kits are my favorite. I have had good luck with the less expensive versions of these but the no slip is what really keeps me buying these when I need them. With no slip it's nearly fool proof way to whiten your teeth to dental office/treatment quality for nearly 1/5 of average costs!

I really love these white strips they work fast and leave me with minimal to no tooth sensitivity.. It is cheaper than actually going to a dentist and getting them done. I have recommended this to all my friends and family because it works so well.. Worth the price last a pretty good amount of time.

Before any event or special occasion I will use these for about a week and I can tell a huge difference in the whiteness of my teeth. They can tend to hurt my gums a bit because my teeth are so sensitive but other than that these are amazing for the price

I couldn't believe how beautiful my smile is after using the Crest 3D Professional White strips. My co-workers, family and church members all noticed the change. My dentist will only see me once a year now. Sweet baby Jesus...My smile is white as Frosty the snow man

After using this product I can honestly say that it works. My teeth were noticeably whiter.The application is relatively easy.The cost is on the higher end,but cheaper and quicker than a professional clean at the dentist. I would not recommend prolong use because a lot whites can make enamel weaker,thus causing sensitivity;and that is a whole other problem. I would recommend this to a friend.

I used Crest White Strips when they first came out, and they worked wonders. But, these 3D Advanced Seal strips are the new and improved version! These strips stay in place, and now I can talk while wearing the strips! (Before it was a challenge to talk while wearing the strips). With these new 3D White Srips there is no uncomfortable flavor even after I remove the strips. Best of all, I noticed a color difference with my teeth after just two uses! Totally recomend these to anyone who needs to brighten up a smile!! :D

I used these whitestrips and I was very surprised to see that you are able to see a change right away. At first they can feel very uncomfortable but then you get used to them. I do believe that they are expensive for you to repurchase over and over again. Overall, I was satisfied because you were able to see the difference in your teeth. 

All I can say is I am totally blown away by the results I have gotten so far. I am a die hard starbucks fan and it was starting to show by my smile. I would notice in pictures my smile looked dull and not very white at all. About 6 years ago I went and had my teeth whitened at the dentist and it could not even begin to touch what the crest white strips have done!! I am thrilled with the results after only 3 days and it's only going to get better! :) If you have ever wanted a whiter, brighter smile, you will NOT be disappointed with the professional 3D strips!!

My doctor gives these away after our patients do in office whitening treatments. I've done a few at my office and definitely enjoy these, there not harsh and easy to use. I recommend these over all other brands. But it definitely helps keep my teeth white especially after an office whitening. Invest in this product to keep your smile whiter.

I'm 5 days into this 20 day process and I've already noticed a difference. These strips are pretty easy to apply, and they stay put. I find that it helps to dry the teeth off before applying and to lay on my back so that saliva doesn't interfere. So far I'm very impressed and I can't wait to see the results at the end of the 20 days.
