Query: Disappointing

I am disappointed with the durability of this product. The bottom of the bowl of the chopper attachment cracked on the second use and the housing of the primary immersion chopper/blender attachment was separating on a recent use. I have only used my Cuisinart Smart Stick about 10 times. Clearly, this product was not built to normal Cuisinart standards. I have the tradidtional food processor, a Cuisinart coffee maker and a toaster -- love them all, so I was excited about the Smart Stick. It's really not so Smart.
