content: This is my KitchenAid Professional mixer. The first one works just fine, but I bake a lot and sometimes I need two machines on the line. The variety of speeds makes it work for amy job you might have. I use this machine for mixing up hamburgers, my secret bbq sauce recipe, rolls, cakes, breads, etc. On valentines day I used my mixer to make 12 dozens rolls for a local church. It's just a great machine.
