Not as good as they used to be...
My mom has had her KitchenAid mixer for 30 years without issue. This is my 2nd round in a few years due to quality. I like the size of the pro mixer but find attaching the bowl and the paddle to be less user friendly than the standard size mixer. I also don't think the quality is what it used to be. It is functional but won't be one that I keep for years.
