Pros:Powerful enough for the average cook, easy to use, easy to clean.
Cons:None that I can think of.
The Bottom Line: If you have the funds and want a great mixer, then get a Kitchen Aid.
My husband and I are avid cooks. He has been a professional chef and I'm just an enthusiastic amateur. Both of us had wanted a KitchenAid mixer for a while, so after a while, we broke down and bought one. We have not been sorry a single second.
Our mixer is plain old reliable white. It came with the standard attachments. Our first job for it was a simple cake mix, but it has since been used to make whipped cream, bread, muffins, and fondant. The only thing I've put in that gave it any challenge was the fondant. It is gooey stuff and although the mixer did the job, I got the distinct feeling that I was taxing it, as the motor began to smell "hot". If you are a heavy volume baker or like to make fondant, you may want to go with a bigger motor. That being said, the mixer is more than game for the average bread dough and soupier batters and doughs are no problem.
The beaters are easy to switch out and the controls could not be simpler. Clean up is a breeze. I cannot find fault with this mixer. If you don't own one yet, you should.
We have not purchased any attachments, but are looking to getting a meat grinder and pasta maker.
