I bought this a few weeks ago. The mechanical pencil and unfold-able pin are
excellent; I didn't need to fumble around with those little set screws. The
die-cast frame was very poor quality, however. The pencil arm broke off at the
hinge when I was folding it back up. I looked at the part that broke off and saw
a casting flaw where more than 50% of the metal was absent. Since this was the
narrowest part of the arm, its little surprise that it broke after a few weeks
of regular use. My compass is now unusable.
