This is a great mixer, and definitely a step up from even other KitchenAid mixers. My previous model was KitchenAid's 5 Speed model, and while it lasted me a long and faithful time, it was a bit down on power, and the speed transitions between the different settings were not smooth. This 9-speed is almost as powerful as the new and popular immersion blenders (or boat-motors, as Emeril would say), but the smooth electronic transitioning between 9 different speeds gives the user a great deal of control which will prevent you from over-beating stuff.KitchenAid's patented beaters remain the best around in terms of maximum air incorporation into eggs or batter that you are working on. The electronic speed control is a flat and integrated switch, the whole surface of the mixer with the exception of the ejection nob is now one smooth unit that makes it extremely easy to clean. The mixer is not super light, but not annoyingly heavy, either, so you won't tire out on those longer 8-10 minute mixing steps that some cakes require
