After 20 years after I replaced my old Bosch kitchen appliance with a new one, I decided to keep me next to a plastic also Edelstahlrührschüssel because my old (plastic) bowl was pretty scraped through the whisk. In operation, there is nothing to complain about, the whisk not hit and do with it no more noise than normal, and the bowl is hygienic. But where I see potential for improvement is in the form itself: the margin is not very wide, making it the bowl (the quite a weight has) hard to keep if, for example pouring the batter into the mold (it occurred to me sometimes even out of hand). This is with the downturned edge of the plastic bowl, which you can take good, much better resolved. Furthermore fit metal and plastic bowls not fit into one another. Metal bowl placed in the plastic bowl, then stuck so that you get them barely apart, plastic in the metal bowl is not deep down, so that the tower is unnecessarily high and thus can be difficult housed.
