Product review (3 stars): Bad stainless steel.  Good company.
I purchased mine from Costco.  I'm not sure if the Costco batch was made with inferior stainless steel, because mine rusted within a few months of use.  Though I live in a warm, humid climate, it still should not have rusted that fast, that severely, or at all!  The flat pieces were not affected by rust as much, but the wire rack itself rusted entirely.  I threw it away eventually; it looked gross.

The product itself gets a 2.  It's a good design - simple, classic and functional.  You can stack quite a bit of dishes in it.  Ample space in the utensil slots.  Water drains well.  BIG BIG points deduction (and only points deduction) -- poor quality stainless steel, that isn't stainless at all.

Customer Service gets a 5.  I emailed KitchenAid, and was promptly replied within a day or two.  (surprised me, honestly).  They apologized and thanked for feedback, and gave me credit towards an e-store that carried an identical product.  The credit itself wasn't enough to cover the cost, and I would've had to pay the difference plus shipping.  I ended up not taking their offer and bought a SimpleHuman (very happy with it, no rust).  Nevertheless, I was impressed with their response time, and that they stood by their product and customer.  Kudos for being a responsible company.
