Ive only had paint through mine, but did think its a bit odd for one of the detents to be sliced off basically, but the other was fine. Link to having a QEV in it? Faster cycling = more wear for detents?
Ive finally got my CAD package loaded up correctly so will have things going.
The Kila ones ive heard mixed reviews of, problems with magnets etc, but same with NDZ however theyve recently been revised which is why they havent been available anywhere.
