When I wanted to get a newer 0.9 mm pencil, this one happened to be available and as I like my other similar Rotrings I bought it and is satisfied with it.
Construction is, as expected, solid and well executed. The cylindrical part nearest the tip is cross cut grooved for a good and comfortable grip.
Near the push button mechanism, which includes an eraser, there's a ring with a window you can rotate to display which lead hardness you're using.
It weighs 20 g, is 140 mm long overall, when in a pocket it protrudes 20 mm over the clip, the balance point is 75 mm from the tip and it's 8-9 mm in "diameter" (most of the body is hexagonal).
