Product review (4 stars): Tiny and hard to turn, but does the trick
Used to replace timer knob on a dryer that needed part WE01X10082, with KIP2210 stamped inside. The GE dryer model number is DSXH43EF0WW.

The actual replacement knob for this dryer is almost $40 on amazon and everywhere else... for a stinkin' little plastic knob.... so I gave this $8 one a shot. This knob is closer in size to the other knobs on the left of my dryer. It looks really funny in the timer spot because it's way smaller than it should be.

It WORKS, but it's really hard to get it to start turning. But that's probably how I broke the original knob in the first place. I just moved into this apartment and started using this dryer so maybe it just doesn't like me.
