Query: GREAT!!............when it works

i bought this blender because i thought it was a pretty cool concept to have recipes at your fingertips while mixing drinks or what have you. i loved how my smoothies came out with this thing. but i have used it less than 10 times and it isn't working at all anymore! the blades froze. the recipe screen still works but what good is that when the blender doesn't work?! don't buy this. i paid about $50 for it and it has turned out to be an absolute waste of money. very disappointing. i guess i'm going to have to search for replacement parts as i can't return it and it's practically brand new.
