A substitute thermometer was delivered and not the Whirlpool brand described/illustrated. I received a "FOX RUN" brand refrigerator/freezer thermometer that has no color coded freezer and refrigerator recommended temperature ranges marked on the dial, has no notched hook for hanging the unit on a wire rack, and has a different temperature range (-20 to plus 80 deg. F). However, the unit is stable on its stand and displays temperature accurately compared to other thermometers I have, so I'll keep it. I'm just disappointed that Amazon.com would permit a bait and switch item to be shipped, especially with the identical item number: 8171720. The substituted thermometer was made in China for : Fox Run Craftsmen, Ivyland, PA 18974 and although it has the identical item number label placed on it, has no reference whatsoever to Whirlpool. Can't help thinking about how much extra profit (%) is being made from selling a cheap substitute.
