Looks cool. Weighs 158 grams without threaded adapter piece.
There was a small smudge/dirt spot UNDER the clear coat right on top. Not too noticeable, but still a bit of an annoyance.
The adapters are okay, but the threads inside the knob itself are a mess... It took over an hour to clean up the threading and get the appropriate adapter piece screwed in, as I didn't have the right size tap to rethread it. It never went in completely... Was only able to screw it in to the point where about 3/4 of the threads were meshing. Hopefully it won't snap while in use.
Can't speak to how hot it might get in the sun. Will know tomorrow. If no update, consider it tolerable.
