I received the product for review from the Product Review Club, I must say Im a bit of a sceptic when it comes to whitening products, but these worked great! I did notice a change in the color of my teeth and it wasnt too uncomfortable to wear for the 2 hours. Plus the convience of 2 hours worked out well in my busy schedule. I did not get any sensitivity from the strips although it does state you might. Overall I would definately use them again.

I received the Crest 3D Whitestrips in the mail and used them for five days. I didn't to used the seven days as my teeth are noticebly whiter and cleaner looking. I loved that they stuck really well to my teeth during the two hour process. I have tried other white strips before and they slip off my teeth before the time is up. I even was able to drink water with the 3D Stripes and they still stuck to my teeth. I did have some trouble pulling them off as they stick very well. I also liked that the gel wasn't horrible tasting like others I have tried. I didn't have any bad taste in my mouth and the gel that was left over on my teeth came off easily by brushing them. I will be buying this product again in a few months to whiten up my smile again!

Hi, I was one of the few who were chosen to experience the effectiveness of these strips. I feel that they did what they were made for. For convenience sakes, it was great. I did however have a small amount of tooth sensitivety, so all I did was skip a day and continued on. I will purchase these again in 6 months as it says on the box to do again.

I;m a big tea drinker and I have found that over the years my teeth had lost some of it's whiteness and I really wanted to have the same white teeth that i had on my wedding day, so I bought the 3D white strips to try to whiten them as we were going to celebrate our 25th wedding anniversay and to my amazement it litned them 3 shades of white.

I loved these!
My teeth look so nice...i was worried about them making my teeth hurt but they didn't.
I have tried other brands and they made my teeth ache :(
These ones will be my first choice for sure!

I have used Crest strips on and off for a few years now - the classic ones and these ones. They work great especially if you use them every day for a few days.

I don't always do the 7-day treatment because I find it too much for my teeth (they can get sensitive), however, even after a few days I can tell a difference in the whiteness of my teeth.

They are a little pricey, so I try to buy them when they are on sale. I love using before an event to make my smile ever better.

I received this product for free to test from ChickAdvisor! This product is amazing, I normally have to take strips off early due to them falling half off, but these ones stuck right on - I hate that they have to be worn for so long at a time but I understood why this was once I saw the results, after just two times using them my teeth were significantly whiter than they were before - I won't lie I was a little skeptical that they would work quickly because strips I have used in the past have taken at least a week to start to show desired results. I especially loved the way they stuck to my teeth - I went to the bank and came home with them on and no one even noticed or said a word! I almost ate with them on because I had forgotten they were there. I have already recommended these to my Mom as well as a few friends, they are always using Crest WhiteStrips so I think these ones would be perfect for them (they're impatient like me and like to see results quick LOL)

I've tried other whitening products before, and I have to say that I liked them better than this one. This product's two hour time frame turned me off immediately. Two hours just seems like a very long time to be so uncomfortable, when other products offer only a half an hour wait time. Further, the sensitivity that I experienced was far worse than the sensitivity I had with any other whitening product. Another thing to note was that after the first few days, I had trouble getting the bottom strips to stick to my teeth, making the whole process rather uncomfortable for the last few days. In good news, my teeth did end up very white, which is obviously the goal of the product, so it did what it says it would do!

I received this product as a part of the trial test group. This product was extremely simple to use. As others have commented, the most difficult part is trying to schedule in 2 hours every day to complete the treatment. My only other negative comment about this product is that, because my teeth are not perfectly straight, applying these strips can be a touch on the tricky side. However, that aside, this product works great. After the first treatment I was able to see mild results but, by the end of the week, the difference was definitely noticeable. I think I had expected to see a bit more of a change but, nonetheless, the change that did occur wad definitely noticeable. The only other treatment that I have tried, aside from whitening toothpaste, was the the Crest Whitestrips that you use once every 4 months. Obviously, as this is a more intense treatment, the difference was more noticeable with this trial as opposed to the previous one.

All in all, although a touch pricey, I would definitely recommend this to others and will certainly consider purchasing this product in the future.

I have used Crest White Strips several times and have always been pleased with the results.

Thanks
