Product review (5 stars): Excellent pricing / Quality parts!
Packaging didn't have Whirlpool (or FSP) logo, just a computer printed label that said Whirlpool with the part number.  I'm not saying it was a knock-off - I'm convinced that it's authentic.  It looked and felt like a genuine Whirlpool part.  Excellent quality, perfect fit, only time will tell about long-term performance, but I installed it with a feeling of confidence that this part will hold up for years.
