Product review (5 stars): More expensive than some of the others but this one is the real deal
Installed and working like a champ!  No way to tell how long it will last but the other Whirlpool branded ice makers I've had all went years without trouble so hopefully this one will too.  My particular ice make had the Whirlpool logo on the box and is an EXACT duplicate of the one it replaced.  It sounds like some reported not getting the real deal but mine is authentic.
