Product review (1 stars): Fix it with gorilla glue replacements are cheap plastic
Had to buy it since the original wore out.  No good as the replacements are all plastic and the Dryer time has a stiff turn to it cracking both knobs I purchased at a store and on line.  I actually had to replace the timer unit as it wore down the shaft.  So as a suggestion to all of you before you spend over a $100.  When it cracks the first time, buy gorilla glue for $5 and glue the knob lining it up properly to the metal shaft of the time and so far I have been good to go for quite some time and no issues.
