Query: Not so great

I have a 25 year old Kitchenaid which in my estimation is gold standard for home-kitchen stand mixers, and I used to cook professionally so I've used a few. This so-called shield, however, doesn't measure up to the brand standard. It is not as snug as it ought to be, and powdery ingredients fly out from under where it ought to seal to the bowl. The problem would be realtively easy to resolve with a rubber or silicone gasket to make an actual seal, but they haven't bothered despite the products perpetually mediocre reviews on most sites. Cooks who own Kitchenaid mixers are pretty serious about their cooking and their issues should be given the attention they merit. Wake up Kitchenaid.
