The kitchen aid mixer is a wonderful mixer, in terms of blending, mixing, whipping, kneading etc. The job is always well done. I bought the Pro 5 because it has a 14 cup flour capacity, and I used once a week to make bread. But there was always a smell when I kneaded the bread, which suggested that the engine was overheating. I returned the first mixer to the store after one month because of this and exchanged it for a new one. The new one had the same issue, but when I went on-line I realized that this was considered normal. After using it for one year & two months, it suddenly stopped working. No grinding, strange noises, etc. It just quit. I called Kitchen Aid (whirlpool) and discovered that they have a 1 year warranty. After spending $500 on this mixer, I am extremely disappointed to discover that they only guarentee their product for one year.
