Cons: Cheap components
I'm on my second unit. The first one got ruined when I used THEIR meat grinder attachment. I DID NOT force product down into the grinder, but, later after I disassembled it, I found that the gears came loose, wore down, whatever. I ended up buying another. But I can guarantee that this will be my last one. I like the capacity and flexibility, but if you can't mix more than a cup of water without risking damage to the unit, what's the point. KitchenAid needs to spend a couple of dollars on making the drive train more durable.
