Firstly, I received this product free to test from Chick Advisor - Thanks - you guys rock!

According to Crest 3D Whitestrips Intensive Professional Effects advertising claims - this product did work to the effect that they said it would for me. Like Crest's other similar whitestrip products, this product worked well for me as well. I drink a lot of green tea as well as the occasional coffee and therefore my teeth can always use a pick me up brightening!

This product exceeded the quality of other whitening products that I have tried (AquaFresh and Listerine) - as they stayed in place longer and better and had a better overall whitening effect.

I would recommend this product to others and I would purchase it again! :)

I received the Crest 3D White Whitestrips Intensive Professional Effects as part of chickadvisor product review club. Woohoo...lucky me! Thank you chickadvisor, totally appreciated.

So I was very excited to try these new whitening strips as they say you will get a whiter smile in a week. The strips were easy to use and place on my teeth. They have to stay on for 2 hours once a day for a week. I liked how snug they were and did not slip off in the 2 hour period. I was still able to sip water through a straw if needed. I did experience some mild tooth sensitivity when using these Crest® Whitestrips. I bought some sensodyne toothpaste to use for the week while I was using the Whitestrips and that seemed to help a lot.

Yes my teeth certainly look whiter! Hooray! Easy to use and quick to see results. I have tried other whitening products and this is far superior and I would definitely recommend this product to others as well.

I only used the strips for 3 days..The 1st day everything went normal the 2nd day was a little bit different I started feeling alot of sensitivity , On the 3rd day my Teeth began to hurt (very sensitive) and I stopped using them..But the effectiveness of the strips were great , They made my teeth brighter and whiter ..I am going to use the 4 other strips but only every few days so my teeth are not so sensitive after use

Overall I was quite impressed with Crest 3D White Whitestrips Intensive Professional Effects.

The strips are easy to apply and stay on well. I also liked that they made the bottom strip longer as I have a very wide smile and strips in the past have not covered as well as I would have liked. These, however, were the perfect length.

2 hours does feel a bit long when you are wearing them. But I found it's all about finding the right timing to put them on and then time flies. For me it was settling in to do some paperwork or editing in my home office.

I did experience some slight sensitivity the next day but not enough to be a problem in any way.

For me, the level of whitening wasn't extreme but was definitely noticeable. And it was the perfect time to test them out as I had a lot of events coming up. I was happy for the extra help in boosting the shine and appearance of my (now) pearly whites.

In my opinion, this is a great product.

I recieved this product from the product review club.

The professional effects whitening strips work like magic. Before trying these I had moderately yellow teeth (a result of smoking/coffee/tea) but now they are pearly white! These are the only strips that have had such a drastic improvement. I've used whitening tooth paste and strips in the past but never got the results that professional effects has given. I've definately recommend this product to a friend and will be buying these for xmas stocking stuffers!!

I really did not like having these on my teeth for 2 hours! It was way too long but that being said, they had a pretty noticeable impact. My teeth are definitely whiter and it was pretty great progress for only having to fool around with these things for 1 week. On the positive side the strips stuck like crazy and didnt shift around at all while I had them on which was pretty surprising and awesome. I would recommend it if you had the money and the patience or needed whiter teeth asap. Not bad and pretty sweet to have been able to test them :)

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.

I received this item as part of the product review club.

I found that this item performed well as stated on the packaging and advertisement. The results were immediate and it was easy to use. I have used whitening trays and toothpastes that were messy and ineffective. This product did the job, and did it well.

This product it one of the better products that I have used for whitening. I found that I could see a difference right away as compared with other kits that i have used in the past that did not show much improvement.

I would consider buying this product again. It is pricey but I found the results to be worth it. I have recommended this product to several brides to be.

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.
