Good quality
Nice knobs. They were a bit tight on the shaft initially but loosened up after a few uses.

Color varies
Functionality is fine, but the black shade was slightly lighter than expected compared to my other gear.

Classic look
Exactly what I needed for my custom pedal. The matte finish avoids fingerprints nicely.
