Product review (5 stars): The real McCoy: OEM Whirpool element, just like the original,  and easily replaced.
I'm happy to report that I did indeed receive an authentic OEM Whirlpool heating element, just as described and pictured.  Yes, it had the stamped  FSP mark on it ("An abbreviation for Factory Specification Parts. Used by Whirlpool to differentiate genuine factory replacement parts from those of after market or universal replacement parts.")  There are a number of off-brand knock-offs available elsewhere on Amazon, most at significantly lower prices, so make sure you know what you're getting.  If you're getting a knock-off from THIS listing, you didn't get the right part.

The element was identical to the one taken from my Kenmore dryer (well, except this one did not have the open coil that caused the failure, of course!).  The whole replacement process could not have been easier -- check YouTube for any of several very helpful videos on the procedure.  Most of the work was in the guilty and long-overdue lint cleanup.  The dryer is back in operation after minimal downtime, thanks to Amazon Prime 1-day shipping.
