It has a great flavor and whitens really well
I got a free full size sample from Smiley360!  It has a great flavor and whitens really well.  The only draw back that I had was that it doesn't foam up like my usual toothpaste.  But if I brush a second time this toothpaste works wonders!  It also helps to repel my coffee in the mornings from staining my teeth (I had less yellowing after longer use after drinking coffee!).
