Bests & Worsts Reviews from Amazon

I have had this mixer for 5 vyears and use it occasionaly. The seal on the mixer shaft leaks oil into the bowl. KitchenAid says this is normal and one should use the mixer at least once a week to stop the leakage. This is a poor solution to the problem! This seal on the shaft needs a redesign. Be aware of this problem. This is a common problem. Check the internet to find other comments.
