Product review (5 stars): Fits perfectly to my Whirlpool Duet dryer (2005 version)
I accidently broke the knob on our dryer, and this fits just right. It came in a whirlpool plastic bag. The color is a very light blue, and not grey as the picture might suggest. It really didn't matter for me though.

It was easy to install. I just needed to remove the broken knob and press the new knob in the correct position. It fits like a glove, and this is the best price I could find out there.
