Query: Do not buy this mixer

Do NOT buy this mixer. Ours broke after only one year of use. Oil began to leak around the attachment hub and it began to make a grinding noise. While we were using ours primarily for kneading, we never exceeded the 14 cup limit on page 54 of the manual. Suffice to say, this is a product with built-in obsolescence.
