I already have a Braun MQ9 stick blender system. Unfortunately the gear box on the 6 cup food processor quit. The good news is that this Braun MQ7 set is interchangeable with my MQ9 handheld motor. The only way I could get a replacement food processor lid was to get a whole new system. I wish parts were available. I looked at getting a different food processor but I LOVE this system. It is very convenient to have one motor and to easily switch from blending to chopping to mashing to whipping.
