Summary: Great strip, little to no whitening for me
Comment: I give the strips five stars, but I'm rating them at two stars because I didn't notice any change in my teeth. With every other whitening strip I've used over the years, I've noticed an improvement (multiple Crest strips and Target's store brand). Not with these, though. However, others here have noted a nice improvement, so perhaps it was just me or a bad package (it had not expired, though). Nothing against Rembrandt, though, as the best whitener I've used was some of their gel.
I think that the application and the adhesion of the strips is superb. These are quite a bit thicker than the Crest strips and will not easily slip off like the Crest strips. These are not unique, though. I had used Target's store brand before these (and since), and these are identical in construction except that Target's strips are blue and these are white. The Target strips are also quite a bit cheaper. So, if you have a Target nearby, I recommend trying their strips first because you get more for less money.
A note for those with sensitive teeth, try using a toothpaste for sensitive teeth for a couple of days before starting the strips and continue to use it while you're using the strips. I use to experience extreme pain when using whitening strips, but I don't now that I use toothpaste for sensitive teeth during whitening. I've used Colgate, Crest, and Sensodyne - they all work the same for me.
