Product review (5 stars): Doesn't bother me since it works great and saved a few $ over white
Works perfectly! Dryer time adjusts correctly.  Old knob had broken inside, so knob slid around and wouldn't start dryer time.  Before ordering, I hadn't noticed this knob is medium grey with black arrow.  Old knob was white with red arrow.  So, if the color is important, be sure to note the color before ordering.  Doesn't bother me since it works great and saved a few $ over white!
