I love my Bosch mixer, and most of the attachments for it. Unfortunately, this one is a loser. This is the issue. It is designed so that you can not put the processor on the base unless the lid is on and secured into the latched position. Once you put the lid on, and then mount the unit to the mixer, you can not take the lid off without removing the unit from the mixer. As you know, when you are using a food processor you often need to use a spatula to scrape things off the sides. This turns into a tedious and time consuming process. Also, when the unit sits on the countertop, not mounted to the mixer, it is very unstable and easy to turn over.
I really wanted to love this as much as my other Bosch products, but am sad to say that it is so cumbersome to use that it is really useless. I am going to get rid of it, and go back to a stand alone unit.
