I do love the scraper to keep the stuck bits moving for further processing.  Only problem I had was using with items containing liquid, such as canned tomatoes, and the container was not watertight.  This is kind of a big problem because liquid was spattering out from under the lid during processing.  I decided to keep it though, and I'm just very careful to make sure the lid is fitted very tight before I turn it on.  I would have also like to have a pouring spout for easier pouring.
