I like the feel of the rubber grip, but it does attract a lot of lint. The
diameter is about 10mm, which I prefer. I don't like my pencils thinner than
10mm, it's uncomfortable after long use. I use the Uni-ball Hi-Uni Hi-Density
Pencil Lead HB lead and this lead significantly reduced lead breakage. The S5
series is very "clicky". On several occasions, I had to click about 20+ times
for the lead to come out. I had to push the lead from the point, which is the
opposite. Maybe it's defective? Regardless, I like this pencil very much.
Drafting mechanical pencils write much better than cheaper mechanical pencils.
