As I'd never used a whitening product before, I was excited to give these a try. They were a little tricky to peel apart. Once on, they felt fairly secure, I didn't have any troubles with them coming off. They foamed quite a bit with me, I expected some as it's a peroxide product, but I found it to be a bit excessive. There wasn't much taste to them, they were just a little gooey feeling.
After the two hours I peeled them off without much difficulty. The whitening product was rather hard to get off of my teeth. My teeth really hadn't whitened at all with the exception of a couple of white spots on one tooth. My teeth weren't sensitive during the treatment, but around 6 hours later they got extremely sensitive. This disappeared within 12 hours. At most my teeth are only about half a shade lighter. I was extremely disappointed with this product. For the price I'd expect much better results.

i didnt get to really keep the strips on for the alloted time because after about half an hour my teeth started to ache so terribly i had to take the strips off so i cant say they are good or not good per say but i know they are not for me my teeth hurt for at least 2 days so this is something i would not be able to use for that reason alone and i am thamkful i now know this so that i didnt go out and spend all the money on it, on the positive side even though i only had them on for half an hour i did see a slight change in the color of my teeth so they do work, i had little white spots on areas of my teeth but that went away and i was able to see a difference in that short time

This product is very easy to use. I loved how well it hugged my teeth the entire time the strips were on. I didn't find it to have any taste, which was extremely nice. I also loved that none of the product leaked into my mouth.

After removing the strips however, I did not see much of a difference in the whiteness of my teeth. They did feel extremely clean though. The down side was my teeth ached so badly I actually had to take a couple of Advil.

P.S. - While I did not see an immediate result in the whiteness of my teeth, I did notice a couple of days later they seemed to be considerably whiter. Not sure why it would have had such a delayed reaction for me.

I've previously used other Crest White Strips where you wear them for 30 mins for a few days. My teeth did look whiter at the end of the treatments. I guess for these ones the 30 mins over a few days are crammed into 2 hrs in one day. Unfortunately I didn't really see much of a difference. They might be a little whiter but that could be me just hoping it's working. Even if they are a little whiter it's not that significant.

I do have sensitive teeth and after removing the strips my teeth are sensitive. I have had this with previous white strips as well so I expected it to happen. The sensitivity didn't start until after I removed the strips though. White the strips are on I didn't feel any discomfort.

Another aspect that I didn't like about these strips are that you have to wear them for 2 hours. That's a long time. I had to find the appropriate time period to where them. I kinda prefer the shorter time period over a few days because it's easier for me to find 30 mins a day as opposed to 2 hours.

Overall I probably wouldn't by this product again. I didn't get really great results and it's pretty expensive. The package is also for a whole year which is a long time. You might lose them in that time frame.

Thank you for the opportunity to try these White strips! I have never whitened my teeth so was really looking forward to trying them. They were very easy to apply and stayed on for the 2 hours. I have to say though that I was disappointed in the results. I was expecting to notice a big difference in appearance but really did not see any significant one. My husband said my teeth looked brighter! I normally have sensitive teeth so was worried they would be more so but did not notice any. I thought it would have a taste but nothing so that is good. Now I can't wait to try them again in 3 months to see if there is any change.I think the price is a bit high but overall this is a very convenient product and super easy to use.

I had tried some white strips a few years ago when they first came out. So was interested in seeing if they had changed much. I have to say that they did stay on my teeth better than they used to and that there wasn't such a strong taste. I wish I had taken before and after photos as after the application I didn't notice any difference. I thought that I would see a bigger difference but unfortunately there wasn't. If I was to purchase white strips in the future I think I would spend a little more money and get the Advanced Vivid.

I was excited to try this product as I am always trying different products to whiten my teeth but find the process lengthy and tedious. The instructions were basic and straightforward. The application was easy and not messy. However, after 30 minutes, it was starting to bother me...no tooth pain just build up of saliva and you could taste the gel. Once the 2 hours done, you had to rinse b/c the gel made your mouth dry. I noticed a slight difference in my teeth (a few shade lighter) but I think i was expecting a more drastic difference. The next day, my teeth had a light tingling sensation but it passed by the end of the day. I will give it another chance in the next few months but i may stick to the 7 day treatments where I have seen better results.

I have only used another whitening treatment in the past (I don't recall the name brand, but it was years ago and all I remember was squeezing some gel onto a rubber mouthpiece). I was selected, by ChickAdvisor, to review this product. This was perfect timing for me because I had a wedding to go to on September 17th; I probably would not have purchased a whitening treatment because of the cost involved. Applying the strips was very simple (although somewhat sticky), and the instructions were simple enough to follow. I really liked that the strips stayed in place, and didn't slide around in the mouth. The taste wasn't pleasant for me, and I did not like the gooey feeling ... even less when it accumulated in the mouth along with the saliva. Ew. In fact, the top strip kind of burned my inner top lip (at the corner of my mouth) ... perhaps it got stuck to it? Removing the strips was easy, and all the gooey residue left behind can be brushed away. I experienced tooth sensitivity while wearing the product, and I the next day I felt an ache in my teeth that wouldn't stop.

The end result: yes, my teeth did appear to gone a couple shades lighter. I must also include that the whiteness was only where the strips had been applied ... no where else.

Would I consider buying this product in the future? I'm not so sure I would. I have always used Crest; however, I'm not so sure that Crest has converted me to their 3D White Whitestrips 2 Hour Express Clan. I experienced a significant amount of discomfort while using the product. I don't think I'd like to experience the same again.

The facts remain:
-you do see a difference in the colour of your teeth

-it is expensive to whiten your teeth, so the cost of this product might be an advantage to some

-teeth sensitivity or discomfort isn't experienced by everyone

Although I wouldn't use Crest 3D White Whitestrips 2 Hour Express again, I would recommend that if someone was interested in whitening their teeth, they might want to give this product a shot. It's not too much time, or too many hours to invest ... and the results might be worth their while.

I'm glad that I received this opportunity; my teeth are just much too sensitive for this. I might consider trying the Crest 3D White Whitestrips Gentle Routine in future.

I received the 2-Hour Whitestrips through the Product Review Club and used them as the package directed. They did stick well to my teeth and were very easy to apply. Unfortunately, I didn't see much of a difference. I have used other whitening products in the past (toothpaste, other whitening systems) and saw much more of a difference. I don't know if I was expecting more of a dramatic difference with the 2-Hour strips as opposed to daily strips or whitening toothpaste, but I found the other Crest products to be much more effective.
I did experience a fair bit of sensitivity problems after using them and will probably just go back to using the toothpaste.

This was my first time using a product like Crest 3D whitestrips. The instructions are fairly straight forward but I thought that adding a detailed picture of where to place the strips in regards to your gumline would have been helpful. I read the warnings on the package about the peroxide level in the strips and was a bit scared to place the strips close to my gums. I ended up placing the bottom strip too far away from my gum line.
My teeth are slightly dis-coloured close to my gumline so I was hoping that the strips would work their magic on that spot. As the bottom strip was too far off my gumline I had no such luck there, the top strip I placed in the correct position and still did not see much of a change as to whiter teeth. I think this product may have whitened the flat front surface of my teeth but not so much that there was a significant enough change in colour to notice. My question to Crest would be, are we supposed to see results after the first trial or after the year? (having used all the strips in the package)
I was going on holidays when I recieved my review package so I used Crest 3D whitestrips in the car on the way to my destination. This was great as it was a long enough time to accomodate the 2hr time requirement without needing to go into public. I recommend from this experience that you are near a bathroom when you take the strips out as they left gummy residue on my teeth which made me want to rinse my mouth out.
Overall I found that this product did not work for me but I am a loyal user of most other Crest products and will continue to use those. As for the whitestrips....I will probably try them again when the 3month time requirement has passed to see if there is any change but will not be purchasing a box on my own.
