Query: a lemon?

I make yoghurt smoothies everyday and bought this mini cuisinart processor to use as a spare when my old mini Krups is dirty. The cuisinart mini is a TERRIBLE machine. It has too many safety features, making it more difficult to position the bowl correctly than the Krups. Spills happen. Also, it is incredibly noisy. This is a significant problem in itself, because you have to run it for what seems like forever to get it do its job, because the cuisinart cannot even puree a banana. After a few minutes of processing, big chunks of banana still remain. I don't have this problem with the Krups. Maybe mine is a lemon, but based on my experience, anything is better than this. By the way, now when I want quicker results with the banana I mash it with a fork first.
