The strips stay on pretty well. Also
I did NOT receive this product as a promotion in exchange for my review.<br /><br />These strips whitened my teeth about three shades, from about a &#34;10&#34; to a &#34;7&#34; on the chart that's included.  Not a dramatic difference, but a noticeable one.  I did not mind the heavier (than Crest strips) residue that some other reviewers complained about; it wasn't hard to get rid of with one brushing after use.  The strips stay on pretty well.  Also, I had no tooth pain as I did with Crest strips.  In fact, I can't actually compare the results w/Crest, because I never finished the full round of the Crest strips because of tooth pain.  That was some years ago; I don't know if they've altered their formula since.<br /><br />For the price, which is between one half and one third what you'd pay for a name brand, I think these whitening strips are worth it.  They are pretty much what my three stars say: OK.
