I received this product as part of Chick Advisor's product review club. I was extermely excited to try it out as I've wanted to purchase it in store but wasn't willing to shell out the cash.

The strips are easy to use and adhere well, even to my never-been-braced imperfect teeth. I was a bit worried that some teeth would turn out whiter than others, but the whitening effect was even throughout. I continued to talk and drink water like normal with the strips on, and they stayed one with my teeth throughout the whole two hours.

After my first use, I noticed whitening right away.. they were at least a shade whiter (quite white to start out with). There was a bit of sensitivity but it was nothing major. After using them for the entire week, there is a definite difference. I have gotten quite a few compliments on how much whiter my smile is. It is definitely a confidence booster and makes me want to smile more! Thank you Chick Advisor for the wonderful opportunity! I will definitely be re-purchasing this, and it is well worth the price.

I use a sensitive whitening toothpaste normally, but wasn't seeing the dramatic results I was kinda hoping for. After getting a regular cleaning at my dentist, I saw a price for their professional whitening kit and considered it even though it was suuuper expensive. After trying the crest 3d whitestrips though, there's no way I'd ever spend more. I'm totally pleased with the results, and am confident that they'll last me for a long time. It seemed like RIGHT after people noticed. Two girls from work were like, "Your teeth are soooo white" and stared at me admiringly for like five minutes. I'm BEYOND happy!
I received this product through the ChickAdvisor Product Review Club.

I received the product from Chick Advisor to test the product. I would have never tried it due to the cost but now that I have witnessed first hand what this product can do, I highly recommend it.

Its a lengthy process, two hours per day for one week. But so worth it. In the end, its the same look after leaving a dentist for a whitening treatment only at a fraction of the cost.

My advise would be to throw them on while your watching a movie (after dinner so you are not craving snacks!) that way its a total distraction from the fact that you are wearing them!

I received this product from the Product Review Club, so I'm very grateful to be able to review this wonderful product.

Instructions were straightforward, application was easy and mess free so that was a plus. However, not being able to eat or drink anything except for water for the 2 hour process is a bit too long! Also, after using it for the third day I began to notice some teeth sensitivity, it went away shortly after a few days so that's why I'm taking off a star for its quality. As for the product itself, it is great if you want to have the effect of professional teeth whitening without breaking the bank. After just one application my teeth were a lot whiter than they were before, and even after the entire process, and drinking tea and soft drinks, my teeth are still relatively white. Would definitely recommend this product if you don't have overly sensitive teeth!

i received Crest 3D White Whitestrips Intensive Professional Effects as part of chick advisor product review club. The product was easy to use, strips applied easily and stayed on for two hours without problem. After the first use my teeth were slightly whiter, but also my teeth became quite sensitive...
But no pain, no gain i decided to continue treatment and now i am glad i did. After 3 days sensitivity was less noticeable and tees become whiter.
After 7 days i can give my verdict: this product is definitely working, sensitivity is gone and my teeth looks much whiter. So if you want to whiten your teeth i would recommend to try it

I received this product from chick advisor for free to review; so thank you first off!
I have always been a skeptic of whitestrips, but crest made me a believer! My teeth were quite yellow; like lemon yellow,from years of smoking, coffee, and staining foods. This product worked amazing!! My teeth are as white as the whites in my eyes now, and I'm no longer self conscious about smiling XD I got amazing results and a huge boost to my confidants!
I have only ever tried toothpaste whitening products and well those are wasted of money in my opinion they did nothing, just made my teeth very sensitive. The whitestrips did NOT make my teeth sensitive, hurt them etc.
I would in a heart beat recommend this product- intact I went out and bought my husband his own box :)

i received these as part of chick advisor product review club. I found that they stayed on really well for the two hours and they were easy to put on, I noticed a little difference after the first application and then a big difference after the second time i tried them, they definately do a great job, i would reccommend these to anyone who is considering a cosmetic whitening treatment!! they are a little pricey 69.99 at london drugs so i for me i wouldnt be willing to pay that much but for anyone who is considering paying hundreds for a professional whitening these are definately the way to go

I received this product free from chick advisor to review. I was very very excited to try these strips out. After checking the instruction on the box and on the included insert I put the first set on right away. I didn't find it very clear which strip was for my top teeth and which for my bottm but did figure it out. Easy to apply. Stayed in place well. Removed easily. I was excited to check out the results!!! Problem is my teeth, which are have never been sensitve before became EXTREMELY sensitive. This sensitivity lasted for 3 days (making drinking and eating uncomfortable) and was gone by about day 5. I read in the instructions that this can happen but wasn't expecting it to be so drastic! Did apply another strip 6 days later. My teeth became sensitive again but not quite as severe. Due to the sensitivity I was not able to apply one a day for seven days. I have used 5 of the strips over several days and have noticed a whiter smile which I am very very pleased with. Due to the discomfort and the cost of these products I would be very hesitant to buy in the future but have to admit the whiter teeth are quite nice.....

Thank you Chick Advisor, for the opportunity to try this amazing whitening product FREE!

I started using the Crest 3D Whitestrips the day they came in the mail, I was so anxious. After reading the instructions (which could be a little more detailed) I popped on the first set of strips. Fairly easy to apply and surprisingly enough they do stay put quite well for 2 hours. After taking them off the first day I noticed a set of brighter whiter teeth already! After only one use! As each day went by there was a noticeable difference. Just WOW. Compared to the effects of basic whitening toothpastes which I had been using in the past.....well ...there really is no comparisson.

Down Side: Tooth sensitivity. This started from the first use and began to ease up by about day 5. I just used a sensitive toothpaste to combat this and it really helped!

I would HIGHLY recommend these to anyone that does not feel like paying for cosmetic whitening. My expectations were far exceeded.

I received this product for free through Chick Advisor product review club, so thank you for that! Hmm...where to begin :) This product is wonderful! it gave me great results and was easy to use. The strips I find stay on really well for those two hours, some days I did have difficulty removing them but most days it was a breeze. A lot of reviewers have been experiencing tooth/gum sensitivity, I also felt this but it went away after the 5th day of applying these strips. Another thing to keep in mind is that it may make your teeth a little discolored at first but I promise you this will go away after 1-2 days :) I didn't see immediate results the first day but by the 3rd day I noticed a difference and so did other people. I have used other whitening products in the past, although I am not a coffee drinker, I do drink a lot of Pepsi which does stain the teeth and although I have fairly white teeth, there is always a need for improvement but I find that other products just didn't give me the results I wanted. Crest 3D White does what it tells you it's going to do, it gives you great results! I will be purchasing these in the near future, although a little pricey it is worth it compared to other product results/dentist treatments!
