“It’s a nice and solid piece, machined out of a billet of aluminium. The mounting is not the greatest as the knob wobbled around even after tightening a few times. Found that you need to use 2 of the rubber sleeves they give you to get a solid fit… cut the top off one of the rubber sleeves and slide it down the shaft, then use another sleeve of similar size and push it into the top of the shaft, this provides a tight fit at the top too, stopping the wobble.
Hope this makes sense.”
