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.

After I received my kit I wanted to try it right away as lately I have been drinking some red wine and noticed my teeth has become less white than usual. (not willing to give up the wine however lol). I put on the strip one night as I was watching TV. It was very easy to apply however I found it bothered me a little once they were both in. I felt uncomfortable to have them in for 10 min and wasn't sure how I would do it for 2 hours but it got better after a while. I made sure I flossed right after I did it for maximum effect and I did notice some improvement. I guess about a week later I noticed that they still looked quite good and I have started to use a whitening toothpaste to make it last longer. I think the price is quite steep for these and not sure if I would actually purchase them but I guess it is cheaer than getting your teeth whitened at the dentist office. Overall it was a good experience.

I recently tried this product on my badly stained teeth ( to much coffee ) They were incredible easy to apply and I could go about my daily buisness while they did there buisness on my teeth for 2 hours. After about half an hour my teeth started to ache and after an hour they down right hurt but I managed to make it through the 2 hours to reveal a SPARKLY WHITE SMILE!! So in the beauty sence they certainly did there job, I think if I whiten my teeth again I will go with a more gradual tooth whitening process . A week later though I am still getting comments on how white my smile is. They do seem a bit pricey but for a speacial occation were you will photographed alot ... its worth it even witth the ache , I should mention the ache lasted a day or so after and is now completly gone .

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

I have only tried the regular Whitestrips before this product. I was always so forgetfull that it would take me weeks to finish a whole 14 day package. That's what I love about these strips. 2 hours and you're done and like others have said they stay put on your teeth. That was the other thing I didn't like about the other kind because they would slip off my teeth and stuff. This time I tried using Sensodyne toothpaste for a few weeks before I used this product and I found that my tooth sensitivity was way better than usual. Sure I still felt it but it went away pretty quickly. This stuff got me about 2 shades or so whiter than I had before and that's exactly what I was hoping for. It's a little expensive, but as others have said there is a whole years worth of treatments in there so if you think about it it's actually cheaper than the 14 day version (which only has one treatments worth) especially if you can buy it using a coupon, and I've seen quite a few coupons around since this product first came into the stores.

I think it's a pretty good option for at home whitening!

I always have trouble with white strips, so these were a bit harder to deal with since you have to leave them on for 2 hours. But, if you're looking for a whitening product to use at home this is a good one.
The strips stick to your teeth very well which is good, but also partly why I found them kind of difficult to put on. Once they touch your teeth they are stuck there so you have to be precise. The strips also seemed a bit too long for me, which is another reason why I had to be extra careful with them.
Waiting with them on for 2 hours was kind of hard for me! Plus the info says not to drink/eat/smoke/sleep with these strips on. But that's not a huge issue at all, especially if you use these at night or another "down" time.
I definitely got some sensitivity as well (which I do already have) but it only lasted for a little while afterwards. My teeth were noticeably whiter, not a lot but at least a shade or two! So these definitely work.
I like the idea of being able to do this at home, and you basically get a year's worth of product as well (if you're the only one using them). The sensitivity is always going to be a deterrent for me with these products, as well as the fact that I don't really like having the feeling of the strips on my teeth, but the results are there, and I would recommend this product for those who want to whiten at home.

I just used the new Crest 3D Whitestrips 2-hour Express and I was quite impressed with the results. As other reviewers have stated, they stick really well to your teeth and there is no unpleasant gloppy gunk on them so you're not swallowing anything nasty. I found that to be a big plus! Sitting with them on your teeth for 2 hours was no problem for me and you could still drink water during that time so that was also a plus. Upon removal, I did notice my teeth looked whiter and they felt very smooth and nice and clean. I did however, start to feel some sensitivity and it lasted over night and the whole of the following day. When I went to bed and brushed my teeth (after day 1), the pain went away and thankfully has not come back. Overall, I feel this is a very good product and I wouldn't hesitate to use it again in 3 months. It was certainly worth a little pain to get such nice white teeth! I will reccommend this product to all of my friends and family.

So I have used this a few times now and I have to say my teeth are definetly whiter. I didn't experience any sensivity or irritation in my gums. My only thing was, it's hard to find 2 hours to sit there with the strips on your teeth but if you can plan around it then it's worth using this product!

I was lucky enough to be able to review this product (thank you review club).

I tried it out this morning....I am pretty 'good' with my teeth and I don't allow them to get too yellow but due to the amount of tea I drink, I do experience some surface staining. This products gives me the extra 'oomph' I need to get rid of those stains!

I did notice my teeth were considerably whiter after using the strips for the required 2 hours. However, consider the trade offs:

My teeth were also EXTREMELY sensitive after using the strips

The strips take a 'death' grip on your teeth so don't freak out if you can't just whip them off. It ain't gonna happen.

So I will give these a thumbs up! They do the job and as long as you aren't doing anything extremely hot or cold for several hours afterward, you should be A-ok!

Thanks to the review club for letting me try these out! Saving a set of strips for the holiday/birthday parties!

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.
