It may be that you just bread dough can go in the other bowl and some essays for further work but only work if a bowl is in the machine, or is it that you have to set up separately for a dough egg white and it is not the old hand mixer wants to take but also the food processor - a second bowl is worthwhile in any case.
Although I prefer stainless steel, the plastic bowl is a financially worthwhile compromise.
It is nice and light and portable, it can be easy to work with.
The only drawback: the gripping edge is not closed down and it could be possibly or similar not remove dough residues as fast as we can from the rest, otherwise easy-care surface.
For me, a practical accessories for food processor.
