The motor is powerful and relatively quiet. We make pasta regularly, and with this machine you can go from mixing the dough to cutting the noodles with the optional KA attachments and boy is it quick! The volume of the bowl is more than adequate for household use and is easy to keep clean. We have also purchased additional attachments over time to increase its versatility. The classic design of this mixer has not changed much in decades and it's not hard to see why. It is not the cheapest mixer on the market, but it is an investment and I wager I will be handing it down to my kids someday.

I've had the same problem. Stops when changing speed and sometimes spontaneously turns off (and not because of overheating). Usually I take it back to the off position and turn it back on and it's fine. It makes me nervous though. So much money for something that's potentially very unreliable. Now it turns off completely if I try to turn it to max speed. It also doesn't mix well, you constantly have to turn it off and scrape down the sides. It doesn't do small quantities at all, even though it's advertised as being able to whisk as little as one egg white. Very disappointed.

Have only recently purchased 7590 but have used it for my bread making. My only disappointment so far is the lack of any printed recipes to get you started as these come with other kitchen aid mixers purchased and I don't want to refer to Internet sites all the time. Having something to start with helps to familiarise yourself with the mixer,it's power and would help with adjusting recipes you already have. The booklet inside does give information on approx mix times etc but I think something more included would be better considering it is a significant outlay for a mixer. Would like a smaller bowl being able to be purchased as often you need to use two different sizes for a recipe.

Just got it days ago, I couldn't really see any problems. But so far the ever ever. Very happy with my purchase and can't wait to try all recipes available. Only difficult is put and take the bowl out of the machine. I'm already looking on YouTube for great recipes to put this machine to feed my family.
