SamIdea CNC Machined Aluminum Alloy Potentiometer Control Knob,6 mm Dia Hole,38mmx25mm

I bought this to use on an arduino project and couldn't be happier. The knob is heavy and solid metal. The machining is well done and and it has a very premium feel. The one thing I will say is the knurling (the "grippy" part of the knob) is sharp. So it grips your fingers almost a little too well. But I think it will subside with use. I may run some light sand paper over it just to take the edge off. But that's minor. I would buy again in a heartbeat.I quick note: this works with any 6mm diameter shaft. I've seen a lot about "D" shafts, but full round shafts and splined shafts work fine too. Mine is a splined shaft.

This was delivered in perfect condition with no cosmetic issues. This knob is solid aluminum so it has some weight to it which provides a very nice feel to the potentiometer. I have already recommended to a friend and now I recommend to you. You won't be disappointed.

I am using this knob as a speed control for an industrial motor. It is beautifully machined of solid aluminum. It looks great, and has a handsome finish. An excellent product.

Feels cheap in hand. Looks OK but does not have that cold to the touch solid metal feel

I was really surprises by the quality of this control knob, excellent machining and finish. Be careful however, its hole is 6mm, not 0.25 inches. Definitely will buy again!!

Looks fantastic. Built like a tank. Not cheap but you get what you pay for. Definitely recommended!

looks good and solid.

Seems well machined, worked perfectly as the master volume knob for a simple passive preamp I built.
