When one has a kitchen aid, opportunities to use it are so numerous that they end up not having enough bowl, or so we spend our time washing to be able to use it again. For my part, I have 3 bowl stainless steel that comes with the robot, the glass, very heavy, unfortunately, and the small stainless steel 3 liters. It is ideal for small preparations to mount a whipped cream, make a single broken 250g pulp, etc ... easy to clean, handle his absence is not a concern and allows it to fit in the large mixer bowl.
