I have been using this product for over a year now and it's great. I have very straight teeth, which helps get every surface. The taste is just fine to me. It makes them taste clean! It does take some getting used to... peeling them off, putting them on, and wearing them, but once you get the hang of it I can talk on the phone just fine. The great thing is the more of them you use, the whiter your teeth get (you don't have to use them all). It really gives you a lot of control. I have had no sensitivity to it, however reading other reviews you might so just use common sense and start off with one and see how it goes. I give it 5 stars.

This tastes awful! I only used it twice on my upper teeth and that was it; it's horrible.

I just started using this product. I have seen a difference in the color of my teeth after using it for the past 10 days. I'm applying it to my top and bottom teeth for 30 minutes, back to back. My teeth were a little sensitive for the first two days. I haven't experienced any discomfort since. I do agree that they should make the strips longer to cover most of your teeth. The reason I would not give this product a 5, is because I wasted at least two of the top strips because they do tend to get tangle up if you do not apply it correctly. They are impossible to untangle. I simply learned to place them over my teeth and use my tongue to wrap it behind my teeth while holding on to the edge of the strip as it's pressed against my teeth. As for the taste, it isn't that bad, beside I wouldn't purchase them if they were any other color than white. I would think in order to give it a flavor you would have to add some type of color to it. This product isn't for everyone.

Holy Cow! After only 2 (yes 2) uses, my teeth were remarkably whiter. Unbelievable. And I didn't even leave the strips on for 30 minutes - more like 15! Great price for the time, effort, and results.

This stuff definitely works. It's whitened my teeth quite a bit. Both my husband and a friend of mine noticed that my teeth looked really white. I'm surprised so many people have complained about the taste, because as far as I can tell it's completely tasteless. It does make my teeth a little sensitive to cold/hot food, but it goes away. First time I tried this (about a year ago) it made them quite sensitive, but when I used it again recently I've had only a mild reaction. Highly recommend this product, unless you have sensitive teeth.

I have been purchasing Crest Whitestrips for the past two years now. I have told that I have the whitest teeth people have ever seen. My dentist told me that my teeth are so white that they are off the charts. I have never used anything other than Crest products. Crest Whitestrips are a guaranteed whiter-smile! I love them, and hopefully I will begin to model for white teeth, all thanks to Crest!

I love these. I used them a while back and everyone commented on my white teeth! I am going to go buy another pack today.

This item quickly began noticeably whitening my teeth--I saw results in only 3 days! I would have given the Crest strips 5 stars; however, those strips are a bit difficult to peel off and can be messy on the fingers. I purchased the Premium Crest Whitestrips. I took a photo before I began and then another photo 14 days later. There was no need for the "before and after" shots, because the whitening was very noticeable. My friends and co-workers noticed, although they could not tell what was different about me. I received comments like "You look younger, "Have you been going to the tanning bed? "You've lost weight, haven't you? and "I don't know what it is about you--whether you're working out or what--but you look mighty fine!"

I am in the middle of a 14 day treatment and have noticed whiter teeth. I am having no problem with sensitivity on my teeth or gums, and the taste isn't all that bad. I wish the strips were just a little bit longer so they cover more of my teeth.

It works but OH MY GOD! It's been 5 hours now and I want to throw myself in front of a Mack truck! I am in so much pain I cannot take it anymore. I can't even use the bottom strips because that would be suicidal. My top teeth hurt so bad I almost want to pull them out of my head. I don't think this is normal pain - maybe I should talk to my dentist or stop using these strips.
