Blending itself is a terrible way to break down ice into crystals, and what's more, it creates unwanted
heat which ruins the effect.  A Jimmy Buffet Frozen Concoction Machine shaves the ice into the blender
and THEN combines-chops up the other ingredients and I ain't ashamed to say it, it kicks A55.  There is
nothing worse in a blended drink than little ice chips.  Say good bye to both ice chips and 2oo bucks.
