I agree! My thought is this: The mechanical pencil is drawing that image because there are a combination of settings on it don't work well for a given use case.

I agree! My thought is this: The mechanical pencil is drawing that image because there are a combination of settings on it don't work well for a given use case. When adjusting the settings, I get poor results, or something breaks. The schematics are available and parts are available for the repair, but the job still takes a while, and I don't know how to do it. My friend has fixed something like it before, but his pencil's controls were different, and some of the tools are no longer available for the way he did it. I would prefer if the pencil worked out of the box, because I'm an artist; not a pencil engineer. I instead buy a pencil from a different brand. It doesn't come in the color I want, but it's good enough, and lets me focus on the drawing. The pencil engineers and enthusiasts keep telling me the customizable mechanical pencil is much better. They love it, have learned its intricacies, and take pride in this.
