Product review (3 stars): Not Stainless Steel
Bought mine at Costco 3 or 4 years ago.  It is  NOT  stainless steel.  I scrubbed mine with scouring pad until most of the rust came off.  But the silver coating came off in several places.  What is under the silver color is something that looks like brass or copper.

I stumbled upon this today as I look (unsuccessfully) for a real stainless-steel dish rack.
