I own this KitchenAid model, and it is the second KA mixer I have owned. This model does a good job, and was a great replacement to my older model K45 of 30+ years. To me, the splash shield is indispensible for adding liquids, which tend to splash out, even at lower speeds. I would never be without my KitchenAid mixer, and it has helped out with cookie dough, decorator cake frostings, breads, quick breads, cakes, and anything else that needs a thorough mixing. The planetary action cannot be beat for efficiency.
