"This is a very nice door knob which looks and feels like quality. However, I've had the reduce the markings as I need two pairs for bifold doors and so far I have had only one pair out of four which are free of defects. The defects include dents which can be felt, poor finishing so the knob didn't have a full chrome polish (both visible and again could feel the rough finish in your hand) and chips in the finish. Annoyingly the faults were all on the same sprung loaded knob so I couldn't switch pairs. I need two matching sets so I'm going to have keep trying. For expensive knobs I expect better quality control."
