Snapped right onto my 1900S with no wobble, and the clicks between levels feel crisp again. Took two minutes to swap the old knob out.

My old dial finally stripped out, and this one dropped straight onto my 1900S with no fuss. The detent clicks feel crisp at each level, so I can actually tell what setting I'm on again.

The replacement knob clicked right onto my 1900S without any wobble, and the detent feel matches the original perfectly. Took maybe ten seconds to swap, and now the intensity dial turns smooth again instead of skipping.
