Product review (4 stars): Good but...
I bought this knob since I understood it would be the same as the OEM knob except for metal construction of the back rather than plastic.  It was but the outer ring (the part you grasp to turn it) was essentially a "hard" plastic rather than the "rubberized" material that was on the original.  It works fine but gripping the original was easier due to the cusioned and "sticky" effect of the "rubberized" outer ring.  Otherwise a very sturdy replacement that does not seem like it will break off in my hand as the original did.  Also, a good price and speedy fulfillment.
