The switches work great. The cables are a plus and really help with prototyping. The only complaint is that the knobs are very hard to press onto the shaft of the switch. You have to press so hard, that you think you are damaging the switch. The knob has a plastic spline inside that is being pressed onto a "D" shaped switch shaft. So that knob is really meant for a splined switch shaft and not for these switches. I may try cutting out some of the plastic splines? Maybe the seller will send me the correct knob?

The encoders and boards look like a good quality, but the included knobs do NOT fit. The encoders have a "D" shaft and the included knobs are for a knurled shaft. They can be forced on the shaft but they wobble.

The encoders look like they are good quality, but like others have reported, the knobs do not fit. Now I am looking for knobs that match with the D shape

Says it comes with nuts and wash, but no go.Also the broads still have the residue left from soldering.
