I feel like I'm not going to be the best reviewer on these trips. I found out after purchasing them that my teeth are quite sensitive to things like this I was able to use them only twice before I had to give away the rest of the box which was disappointing as I wanted water teeth which is why I bought it so for me it was an uneventful purchase that I was unhappy with. But it was not the fault of the product it was my teeth.

The strips wore quite comfortably which was nice but they did nothing for the teeth. I could not see any difference whatsoever.

I've had my teeth professionally whitened many years ago and loved how beautifully white my teeth were. I don't have that kind of money to spend now as a Mom with a family so I thought I'd give these a try. Sadly, it was not a good experience. I suffer with very sensitive teeth and keep it under control using sensitive toothpaste. Using the Crest White strips brought all the painful sensitivity right back and it took a long time for it to go away. I would have loved for these to work because they are fast and cost effective but I think I'll have to spend the money and do it professionally again if I want whiter teeth!

This product has been one that I have tried to use to keep my teeth white. These whitestrips do work well but the pain you'll endure after is totally not worth it! Left my teeth feeling sensitive for a few days after! Save the money & try something else!

Did not work well for me after 3 hours on

I really didn't see much difference in my teeth. I have had my teeth done by the dentist and there was better results. Only used Crest 3D a couple of times the prices are a rip off. Quality none and effectiveness hardly any so sad because it would have been a great product if it had of worked.

I got a box for Christmas and was very disappointed. I did not notice any change in the colour of my teeth

tried it and i have high expectations. what i did is i took pictures of my before and after procedures. pictures are taken both with natural light and indoor lights. when im done and compared the four (2 for each) pictures... there's not that much change... its just like i brush my teeth. and doesn't even smells good. so dissapointed.

I tried this product hoping it wouldnt cause alot of sensitivity. After roughly 20 mins, I had to take the product off. My gums were so sore and continued to be sore for about a day.

I have used whitening products before and never have had such a reaction. I think I need to try a strip that doesnt require to be worn for 2 hours, but I understand the need to wear the strip for 2 hours, so THIS product as its supposed to work that quickly.

I will attempt again but am not optimistic to have a good result. However, I am happy that I was able to try these product.

I was sent this product to review, and I'm so glad I didn't spend money on it. This did absolutely nothing. I left both strips on the specified amount of time, I did everything right and there was absolutely NO difference. I'm not a heavy smoker, I don't drink dark wines and I have generally healthy teeth. SO disappointed.
