I just got 'em... Totally liking them. They're a TOUCH longer, which, I'm a newb, but it seems like they hold more juice... They also really do stay cooler. MUCH cooler. Also, softcaps! I'm liking them all the way around, really. Also came with TWO samples, the Cappucino I think was filled with chocolate though, as I can't tell anything "cappucino" about it, but certainly taste dark chocolate, the espresso isn't bad though. Not sure that I'd buy either of the flavors, but I can't say enough about the Coolcart blanks for my KR808D-1.
