content: I bought the Pro 600 and gave my dependable Classic to my in-laws who never have a stand mixer. Unfortunately even with minimum use, the gearbox on the Pro 600 broke. Since the warranty has expired, Kitchen Aid and Amazon suggested a repair center where I could pay to get it fixed. Big Deal!!!! My old classic runs like new after decades of use...and the new Pro 600 is broken after minimal use. Obviously, Kitchen Aid has changed...it doesn't stand behind it's products. Never again.
