I just busted my kitchen aid. I was whipping up a cream cheese frosting on speed 10 when suddenly a spray of metal shavings shot into the mixing bowl! The gearbox has been oozing a disturbing sludge for about 6 months, but now suddenly it reached the tipping point. It was totally disappointing because I was really looking forward to making a grapefruit zest and orange essence frosting for some cupcakes to eat after lunch. But the good part is that I called kitchen aid and they are going to send me a replacement by fedex right away!
