So I was super excited to use this product! My teeth are normally pretty white, but I think everyones teeth could use a little help! Lets just say I was happy I ate BEFORE i put the strips on! Two hours is a lot longer then I ever remembered! Hahaha!
The strips stayed on super well though....it was awesome...and it made my teeth only a little sensitive! (this went away after about 2 days!)
The results were ok! Yup...just ok...nothing I would run home to tell everyone about...but when you are looking for a quick brighten up before a big event...these are perfect! No waiting 12 days & no slippery strips!
In my opinion they did just what they said they would....I just don't think I'd go out of my way to purchase them!

I think this is a good product to use to brighten your smile. The results were not quite as drastic as I was hoping for but it did definitely lighten my teeth a couple of shades. I did experience a bit of sensitivity the next day but it didn't last long. The strips stuck nicely to my teeth and I didn't have any trouble removing them. I do wish the bottom strip was a little bit longer as I have a very wide smile. The hardest thing for me was finding a 2 hr. block of time to whiten which is why this review is a little late. I didn't find them to be 'invisible' enough to be confident running errands with them on. Overall I was happy with the application and results of Crest Whitestrips 2 hr. Express and would recommend them.

I received the Crest 3D White Whitestrips 2-hour Express as part of the Product Review Club. I was very excited to be chosen to review this product. I have used the regular Crest Whitestrips in the past but I never follow through and use them each day for a whole 2 weeks. I like the idea of a one time 2 hour application. The strips stuck to my teeth well. I did notice my teeth to be whiter after the application. I find the strips more effective than any whitening toothpaste or gum. I did have some tooth sensitivity for about a day after use, so that was the only negative thing. Other than that I would recommend them to friends/family for an effective, convenient, cost effective way to whiten your teeth.

Thank you soooooo much chick advisor for choosing me to be one to rate this product!!!! Since this was my first time to receive something to rate I was extremely excited!!! So once again! Thank you!!! I was really excited to give this product a try as I have tried other teeth whitening products before by crest and gotten great compliments!!! I think this product works great!!!! I love how they have so much more staying power on your teeth! The other strips keep sliding and I find it difficult to be doing other things while having the old strips on. These 2 hour ones stay on good! But I still find it best when I have them on and I am laying down. The part I didn't like about these strips was the pain after!!! My teeth were super sensitive for only one day only but it's not a pleasant feeling at all. other than that, I totally recommend this product to everyone!

I was happy to receive this as part of the product review club. I had used the regular whitestrips in the past, and had found them a bit awkward at first, but easier once you got used to them. I didn't find these ones too uncomfortable, I just find you have to be doing something to distract yourself so you don't focus too much on them. It was a little hard to find the 2 hours when I wouldn't be eating, drinking, or going out of my house, but I eventually figured it out.

My teeth definitely were more sensitive following the application, so if you have very sensitive teeth, you would likely want to avoid these. The results were fairly good, I am interested to see how another application down the road changes them. The price seems high initially, but when you realize it covers an entire year's supply, it is fairly reasonable. However, I am hoping that I can manage to keep track of the rest of my supply for an entire year. Overall, a thumbs up.

As an avid coffee drinker and smoker, I was very excited when I was chosen to review the Crest 3D Whitestrips 2 hour express as part of Chickadvisor's Product Review Club. I was weary of how these would work on me and all the other types of Whitestrips products out there because I do have sensitive teeth and did not want to make them more sensitive, better to have yellow teeth than not be able to eat anything because your teeth hurt.

I can say that after using this product my teeth have become a bit more sensitive, I have been using Sensodyne toothpaste to try and calm that down. So if you are one with sensitive teeth that is something you may be interested in.

In terms of packaging and cost, these are expensive, but you get a YEARS worth in the box, you only have to do this 4x a year, so the results are great for the price.

You leave them on for 2 hours..which I thought, 2 hours?! that long! But you don't really feel them when they are on, and if you have 2 hours to spare while you are doing housework or sitting around watching tv, it's not a big deal.

The whitening was pretty impressive after just one application too. Great product.

I'm a coffee and tea addict and have been wanting to do a professional teeth whitening for years now (except I can't afford it) so I was so ecstatic when I got chosen to write a review for this product!

I like how this is a one year supply of teeth whitening so it definitely helps out with costs from making trips to the dentist and potentially saving hundreds of dollars.

The actual treatment itself was really effective and not that uncomfortable at all, maybe a little sensitive around my top corner gums (it is receding a bit). The strips actually stuck to my teeth instead of sliding around like previous strips, so I was impressed with that. After 2 hours, my teeth are considerably a lot whiter and looking pretty awesome! I'm going to be sharing the one year supply with my husband :) I would definitely recommend this product and would use it again.

I didn't realize until AFTER I received my sample in the mail that I'm not supposed to use this because of pregnancy. NOTE TO MOMS-TO-BE: you may read on some forums that whitening products are okay for pregnancy, but there will also be others (including dentists) who will advise you to avoid. Better to be safe than sorry. And so, I got my husband to try these out instead.

First, the con: the fact that you have to wait a while after you brush your teeth and then have these on for 2 hours is a little inconvenient. We had trouble finding a good chunk of time to do this, when finally my husband decided he'll just do it at work (so unfortunately, I wasn't there to take before and after pics). Aside from that though, I appreciate the fact that you do this once, and then not for another 3 months for the next application.

Overall, my husband was pleased with the product. There was a slight improvement in the whiteness of the teeth. However, compared to other products, it's not that much different in terms of whitening power. This one seemed to stick on better though, so less leaking of the gel (yuck!).

We would consider recommending it to others for the convenience (only a few applications vs 7 or more), but only if it's economical.

Ever since these strip products have come on the market I've been a bit skeptical. I tried them when they first came out and really wasn't impressed. They didn't stick, tasted awful and required multiple applications. I shied away from them for years.

I accepted these new 2 hour strips for the product review club. My teeth don't really need whitening, but a little touch-up couldn't hurt, right?

Well it seems that the strip technology has come a long way in the past few years. These strips adhered well and stayed in place for the whole 2 hours, even through a long phone conversation.

They're a little weird and made me produce more saliva and catch my tongue on the edges a lot, but overall it was a fair price to pay for whiter teeth. I like that you can do it all in one go rather than having to repeat the process for days at a time.

They did a noticeable job of whitening my teeth, so I'll probably use them again in a few months as recommended.

Some drawbacks are that they made my lips & gums sting for a while, and the gunk left on your teeth needs to be brushed off right away. I have a feeling they're expensive, too.

As a smoker and a coffee addict, I jumped at the chance to try these. My birthday is coming up in a few days and what's better than having extra-white teeth on your birthday right?

These strips were incredibly easy to use; they peeled right off the backing and stuck to my teeth no problem. I was able to continue with life as normal while I had them on - no excessive drooling. So far, so good.

About 40 minutes in though, I started to get antsy. I wanted to eat, I wanted to drink, I wanted to smoke! I was tempted to rip them off my teeth right then and there but I forced myself to press on. But two hours felt like two days to me and I tapped out somewhere around an hour and twenty minutes...I couldn't take anymore.

i did get a blast of nasty peroxide taste when I removed the strips; but I wasn't particularly gentle or careful about it so that wasn't my fault. But I'm pleased with the results. My teeth are a bit whiter - not a dramatic difference, but it's visible - and they feel smooth and clean. No white spots and no irritation or sensitivity at all.

I will definitely use these again and I just recommended to a friend that he try them out too. Thanks Chick Advisor!
