*~*~*SPARKLING, SHINY TEETH!!!*~*~*
I just finished my two weeks using Crest Whitestrips.  I was a little skeptical about whether it would work, but after reading the reviews I tried it.  My teeth weren't really bad, but they had a bit a yellow-ish coloring and weren't the brightest.  I swear I noticed a difference after 24 hours!  After the first week, my teeth weren't only white, but they were also shinier.  I'm so glad a spent my money & time on this whitening system!!
