I love these white strips - it's the only brand I'll use. I have tried most, and these are by far the best. The thinner plastic strips allow the gel to leak out into your mouth or up onto your gums causing bad taste, burnt gums, and non-whitened teeth. I can't get these in the local store anymore, so I always buy them from Drugstore.com. My husband and teens use them too. Pros: 1) They stay put. 2) The whitening gel stays inside the strip ON your teeth. 3) Waxy outer part molds well to my teeth so that the gel can get in between teeth. 4) They work! People always ask me if I have my teeth whitened professionally, but I never have. 5) They work - even for a coffee & red wine drinker like me. Cons: Uhhh...

This product does work. I did get white spots, but the trick to that is to use these 30 minutes before bed, remove them before you go to sleep and in the morning the white spots will have blended. Also they whiten pretty well, but the results didn't last as long as I would have like. Thats why it gets a 4 from me.

These are the BEST strips on the market. The Crest strips do not stay on, whereas these wax-type strips can be form-fitted very well. With the whitener already "built" into the strip, it gives tremendous results. I admit to leaving them on longer than recommended, but I've had many, many compliments on my teeth - even from strangers. I have given this product a lot of business because of my referrals.

I LOVE these strips. I've been using them as directed for about 2 years now. I drink lots of coffee and smoke, so these are perfect to keep teeth whiter and brighter between visits to the dentist. They stay in place, and I notice results after just 2 applications. I wish you didn't have to leave them on for half an hour each day, but I really can't complain. The whitening is very even, and the taste is slightly minty - nothing too terrible.

I love these because whiten very well, and stay in place on your teeth - more than I can say for any of the others I've tried. I've never experienced any white spotting on my teeth.

They made me sick--literally. The taste is pure peroxide. It also burned my tongue. I wore them twice and just cant do it anymore. These are pretty thick too. It was like wrapping a piece of chewing gum around my teeth. However, I did see an improvement after the two uses; that's why Im disappointed.

This product made my teeth slightly whiter... in spots. I now have spots of white, which look very strange. I'm not sure if this is caused by the whitening or not, but I also noticed a slight crack in my front tooth, that I never noticed before. This product also caused major sensitivity to my teeth, as well as my gums; which appeared to be slightly torn. I give it 3 stars, for the slight whitening.

Rembrandt Whitening Strips stay on my teeth better than other whitening strips I have tried; the gel also did not seem to come out like other whitening kits. This worked for the lightest to darker discolorations. My teeth look natural and clean after the complete treatment. I would like the lower strip to be longer; otherwise I would have given 5 stars.

I've tried Crest whitening strips and liquid whitening pre-rinse, but the Rembrandt is the best. They stay in place, are easy to apply, and do what they are supposed to do... they whiten your teeth a few shades. Worth the money and better than the other products on the market currently.

I started using Rembrandt whitening strips right after a dental cleaning. My dentist has informed me that it's the best time to use such products because whitening will be more effective after a professional cleaning. I think this is why some people had white spots on their teeth; they may not have had a professional cleaning prior to using this product or other products of this nature. I've been using this product for almost a week and my teeth are considerably whiter. My teeth were not yellow or stained when I started, but it was not as sparkling white as it has become. In addition to the strips, I also use whitening toothpaste for upkeep. One con is that I do feel some sensitivity from using the product, but it is no more than what I felt from using Crest Whitestrips. I was never able to finish using Crest Whitestrips. Overall, I highly recommend this product, and for maximum results - USE AFTER A PROFESSIONAL CLEANING!
