Product review (1 stars): This knob is entirely plastic ... avoid if looking for weighted stainless steel knobs
Entirely plastic.  Listed as an OEM part, but my knobs are weighted stainless steel.  This is supposed to be the replacement, but it it worse that the original knobs.  Other reviews stated this was a metal knob, but perhaps another seller was filling those orders when the original reviews were written for ... this seller is is distributing sub-par parts (QuickShipParts).  This knob is a piece of junk and entirely plastic.
