This is the top-end model that Apex and I have. It`s ridiculously powerful. With a 525-watt motor to handle bread doughs and thick cookie batters, this is KitchenAid`s most powerful stand mixer, a professional-grade appliance with a heavy, rugged, all-metal construction (31.7 pounds) which prevents "counter walk" on the mixer`s rubber feet. It has a 6-quart, polished stainless-steel bowl with an ergonomic handle and a two-piece pouring shield made of heavyweight plastic to provide a large chute for adding ingredients. Accompanying the mixer are a burnished flat beater, a burnished dough hook, and a big wire whip. On the front of the powerhead is a hinged cover for the hub to which KitchenAid`s many mixer accessories attachments.
