Query: Junk

I read reviews complaining that the plastic "teeth" to this blender wears down, rendering the whole thing useless. Well, even with the caveat, I purchased the item and sure enough -- few months later, the teeth wore down and I had to trash the blender and the chopper attachment. I wasn't happy with the blender even before -- it doesn't blend food at the bottom of the cup and the chopper attachment doesn't properly "grip" and chop the food -- but the plastic teeth thing is really ridiculous. An important component that attaches the motor to the blade should really be made better. This is a shoddy piece of equipment and I warn others to stay away. Cuisinart really needs better quality control and should be ashamed.
