I found the Crest Whitestrips very easy to put on and that they stayed in place for the required time.

As for effectiveness, I saw a slight whitening, but not much. Luckily my teeth did not feel sensitive as other advisors had noted.

I do agree that the adhesive, though efficacious, was a lot to get off after the treatment.

Although the Whitestrips did a decent job for the price (in comparison to a salon on dentist's treatment), I did not enjoy the length that I had to wear them for the whitening achieved.

This product worked well, however I didn't like how sensitive it made my teeth. I would recommend it to someone looking for a quick fix, but maybe not to someone who already experiences sensitivity as it can be uncomfortable. Overall, useful product!

I do have to admit that this product works. I could see results right away. However it is very uncomfortable to wear and I hate the residue that comes with it. With that being said, I would recommend it but not to anyone that gags as I had gag reflexes due to the residue.

I was able to test this product out for free thanks to chick advisor and would reccomend it to a friend or a family member who are looking to get whiter teeth without having to break the bank and get it professionally done. It was easy to use with no hassle to put on the strips and there were some results after the application. Something I would definitely use in the future again if needed. Overall great product!

I did like Crest 3d white strips. The only thing is i think they are way to expensive and therefor not worth buying. I did like the fact that it was easy to put on and did not feel like others that i used didnt really feel like i had something on. I did find it hard at some points to have it on for two hours. But i guess you need to have it on for that long. I didnt find i notice that big of a change but i am sure if i used it for a longer period of time i would have

I received this product as part of the Product Review Club. I was very excited to try them since I am getting married in just over 8 months and my teeth could definitely use some brightening. I used as directed for 2 hours one evening and unfortunately my experience was not a good one for 2 reasons:

1. 2 hours is an extremely long time! Can't eat or drink during that time. Although the strips are not overly uncomfortable, it wasn't an enjoyable 2 hours either. It also would have been difficult to find 2 hours every single day for a week that I wasn't going out or doing something (I could talk OK while wearing them but I still wouldn't want to go out in public with them).

2. My teeth were EXTREMELY sensitive for 24 hours after using the strips.

I did notice a slight difference in the color of my teeth, so I'm sure if I could have stood to use the full box they would have looked amazing, but the cons definitely outweighed the pros for me. For someone else they might be ok, I have had problems clenching my teeth in the past so it's possible that made me more susceptible to sensitivity, but it was just too much. I think I will stick to the slower process of whitening toothpaste.

Thank you to Chickadvisor & Crest for letting me try these whitestrips.
I found the strips in this kit to adhere better than other brands, it unfortunately didn't live up to its claim noticeable whitening after 1 treatment . The difference isn’t very dramatic but it is somewhat noticeable at 7 days. Everyone will see different results depending on what your teeth looked like before.

Thanks Chickadvidor for allowing me to test this product. Let me start off by saying this product is not for those with sensitive teeth. By the second day my teeth were hurting..and knowing I had to leave them on for another two hours that night sucked! I also believe that although the strips stayed in place for the two hours it was a very long time to keep the strip on. After the 7 days I do see a difference, my teeth are whiter but also in a lot of pain!

First off, I have photos, but there wasn't a noticeable difference in the photo. There was a difference in person though!
The strips adhered very well. I did find them a little difficult to apply evenly, there seemed to be a wrinkle somewhere along the strip, and the wrinkle caused the gel to leak out, and irritated my tongue.
I had to take a break on day 3 because the pain it caused my teeth. Thankfully the sensitivity has subsided a few days after the week trial.
I didn't find it hard to grab 2 hours to use them, so that wasn't an issue. The biggest problem I had was the tooth pain.
I don't imagine that I would use these again. I think that Crest should include a toothpaste for sensitive teeth for the week that the strips are being used.

I received these for free from the CA Review Club.

I used them for the full 7 days, 2 hours a day. I didn't notice that much of a difference while using them - my bottom teeth were not whitened because the strips kept slipping off. However, they stuck to my top teeth. It did cause quite a bit if sensitivity and caused some white spots to appear on my two front teeth. Because of this,
I would not use this product in the future.
