Product review (5 stars): Works great!
I wasn't sure if this would work on our dryer since other places said it's not compatible with it, but thought I'd give it a try since it's much more reasonably priced than what I found elsewhere that were supposed to be compatible. The knob appears to be slightly smaller than the original, but this doesn't affect its performance. It does have the metal inside, and I'm using it as a control knob. Works great!
