These are great knobs with what feels like solid durability. The dot is basically useless if it disappears below center in the down position. Can't see it. No biggie. Go by sound, not by sight. The only problem I have with it is that the mounting hole is larger than any post I installed it on and if you tighten the set-screw down to hold it in place, it will tilt the knob and make it uneven with the guitar surface. You really have to hold the knob in the position you want it in, then tighten the screw, but not too tightly or it sets the knob on crooked. Maybe it's me, but once I set it straight, It works like intended. Great knob with good friction.
