I got memed into buying one of these

you are insane, adjustable per click lead output is a god send.

Rotring 600 is the best pencil.
Rotring 800 is the worst pencil. I've had 2 (0.5mm) and both break leads no matter the hardness.

To help prevent breaking leads I guess? I have no problems with that on the Graphgear, but that could be because I got it in 0.7mm.
Otherwise I use a Zebra Delguard.
