I received the Crest 3D white whitestrips 2 hour express in the mail as a product tester. The packaging was small and attractive. Inside were 4 foil wrappers. This box is meant to last you one year. Every three months you use one package to retain your "white teeth". Inside each foil wrapper is a bottom and upper teeth strip. Very simple and easy to use just place on the teeth, hold for a few seconds and fold over, so that it can stay in place. For the two hours that I had it on it did not move. There was no taste at all, no chemical or peroxide leaching out, which was so nice. Didn't even seem to mind them on at all, only thing is that it makes you salivate just a little bit more. Also there was no burning or gum pain. Easily a very neat product. You just peel it off your teeth when it is done and I just had to rinse them with water to remove any whitener still on them. My teeth did lighten up a shade for sure. My hubby said he could see a difference. I definitely would recommend this product. Very happy with the job that it did. I would say that for the cost of the product and it lasting you a year worth of treatments, its a great buy.

I've whitened my teeth before, and usually it involves multiple applications over several days to see results, so this 2-hour express version is certainly more convenient. The strips are easy to apply, and not too troublesome to wear (my mouth felt a little dry, but nothing you can't manage.)

Though I didn't do before and after shots, I'd say my teeth were whiter. Unfortunately they were also far more sensitive. My lower teeth actually ached for the rest of the day. I don't normally have sensitive teeth, but this was apparently a bit much for my pearly whites. While I love that I wouldn't have to do it again for 3 months, I'm not sure it will be worth the mouth pain. I might have to switch up for the sensitive teeth version.

I received this as part of the product review club:

I am pleased with this product in general. As for an alternative to going to a specialist and paying hundreds of dollars, this is one of the more effective home whitening kits.

I was slightly nervous at first to apply the strips as my teeth are not perfectly straight, and I've had difficulty with stripe like products before not completely covering my teeth. The size of the crest white stripes were a little more accomodating.

I liked the idea of having to only wear the strips for 2 hours every three months, this is way more likely to actually happen then something you'd have to apply nightly for example.


My teeth were slightly sensitive after the first use, which could have been my application technique, I will find out with my second trial, but I did notice a difference in colouration, and was impressed that I saw a slight difference in only 2 hours!



(as per suggestion from Chick advisor, the box was dented when arrived, and I didn't get a glimpse at the delivery guy ;) )

I was one of the lucky you that got to try the crest 3-d white whitestrips 2 hours express. It was the first time that I was trying something like that. I was very surprise of how easy it is to use it. I tried it over the week-end and I would recommand it.

I'm not sure if my teeth went so much whiter but I could see them more bright then before.

Overall i was very satisfied and i'm happy i have some more for the rest of the year.

Let me state at the outset that I am very famliar with the Crest family. I've used them all, more than once. They all work. They all work well, it's more a question of what is most important to you.

Over the weekend, I met the youngest - 2-Hour Express - for the first time. And before I compare him to his siblings, I'll give him my full attention.

2-Hour Express is exactly what it sounds like. A rapid 2-hour whitening treatment. Although I got my box on Tuesday, I waited until the weekend because who has a 2-hour window these days? I figured I could work them into my routine while doing laundry Saturday morning. The strips seem longer than the other ones. It stuck on well and stayed on for the full 2 hours.

As you can see from the photos - they work (top - before, bottom - after). Pictures don't lie.

I was surprised that my teeth and gums weren't "raw" after the treatment. But I realized I spoke to soon. By Saturday night my teeth were really sensitive. The discomfort was constant and lasted until Sunday night. It's not unexpected, but I'm not sure it's worth the immediate whitening effects. The other systems I've tried may cause a little intermittent sensitivity immediately after, but nothing compared to what I experienced with the express treatment. The good thing is that you only need to use them once every three or four months. '

Taking everything into consideration, I'd recommend them. It's instant, especially if you don't have any sensitivity issues and just want a quick way to brighten your smile. If you're like me, and have sensitive teeth, I would still proceed, but with caution.

Now, as in all families, comparison breeds competition. Since they all work, I would break my advice down like this:

Most cost-effective: Vivid (you give up a little whitening power, but it still works)

Most whitening: Professional Effects (almost always whitens more than her siblings, but costly, even on sale)

Most immediate: 2-Hour Express (you save a little time and get instant gratification, but if you have sensitive teeth it may not be the best)

Most gentle: Gentle Routine (not as potent, and therefore not as effective, but still works)

All though I have only tried one strip treatment so far, I can definitely see a change in the color of my teeth. As for the strip itself, it was easy to apply. One problem I did have was the bottom strip would not stick properly but the stop strip was fine. The price is reasonable considering how expensive it is too whiten your teeth at a dentist. Overall a very good product would be recommending this product to all my friends and family.

This is the first time I have used a whitening strip. My teeth are not perfectly straight and I found that, because of this, I had a difficult time getting the whitestrip, specifically on the bottom, to stay on in the beginning. After they were on however, the process was pretty painless. I had one area where sensitivity was an issue but that was short lived. I do agree with other users however in that by the 2 hour mark, the feeling of saliva under the strips gets to be a bit uncomfortable and it definitely feels good to get the strips off.

As for the results. I have to say, I definitely noticed a difference after taking the strips off. I think part of me was kind of hoping for a more dramatic result but there were definite results, regardless of my hopes, which was exciting.

I will definitely be using this product again and will recommend it to others. Regardless of the slight inconveniences that may have arisen, this product does exactly what it advertises in an effective and efficient manner.

I could only use the strips for one hour for medical reasons, but that one hour made a difference! Cannot wait to see what happens in 2 hours. Even some of the stains that were there after the braces came off were lighter. I only wish the strips were longer to get the back teeth, maybe cut a strip up for the back.

I recently got these Crest 3D Whitestripes through the Review Club. It was great timing because I had a posh wedding to go to and was feeling less than stellar about the whole thing. The very first day I put a set of the strips on, which were very easy to apply, and began timing. They were super-easy to apply and did not slip or stray from my teeth for the entire two hours that they were on. As a matter of fact I had a bit of trouble trying to peel the suckers off my teeth, leaving a small amount of residual goo.

First off, I did not have any tooth sensitivity while wearing the product but I have to admit that the next day there was a dull ache that wouldn't leave my teeth. This only lasted throughout the day and I haven't had any problem since. The two hours didn't seem like an overly long period of time, as i was at home doing very little anyways. Why not whiten teeth while doing laundry!

I have to say that i have in the past used other whitening systems for both 7 and 14 days and have to admit that I saw better results with them. I don;t know if it was because I saw a gradual change in my teeth and so assumed that they were getting alot whiter or that the 2 hour system I was expecting too much of a change and only saw a slight glimmer. I see a small improvement in my teeth and a brighter smile. Just be warned that I did see a few white spots on the front of my teeth (where i panicked alittle but the box does address this) and they did disappear over a period of a day. All in all, I would use this product again as a freshening up of my smile but if I wanted a dazzling whiter set of pearlies I would look elsewhere.

I was selected to review this product. Had I not been selected I may not have bought it on my own as the price would be too much... But on to the review.
I had a 2 hour drive to do so I thought it would be a great time to use the Whitestrips. I didn't feel much of a tingling sensation until right after I took the strips off. Now, 4 hours after the treatment, I'm feeling a bit more tingling but it is very bearable and its the price you pay for having white teeth that only took 2 hours, woohoo.
I don't normally experience sensitivity so I'm hoping that this treatment won't trigger any.
I have previously used the whitestrips that you use once or twice a day and this was very similar except that it was for 2 hours and I only had to do it once.
My teeth do look whiter and I would use this product again.
