I've had this pencil for roughly five months now, and I can say that after
every-day use I would not recommend it for most people.
For durability I would rate this pencil a 5/5, for the full-aluminium doesn't
wear easily, and after 5 months of every day use the only problems I have
encountered are the lettering on the barrel rubbing off some from clip, and the
grip's diamond finished chipping in almost microscopic scratches. The
retractible tip is very solid and at first lead breakage was a problem, but this
was fixed as soon as I removed the factory lead.
For Overall construction I would rate it a 2/5, because of the cheap interior
and the lack of ability to service the parts yourself. There is no way to
unscrew the barrel from the tip and clean it or replace the spring if need be,
but this hasn't really presented any problems so far. The inner lead guide is
cheap plastic though, and bends, scratches. and tears easily. Don't plan on
using the eraser much on this pencil, for you will eventually loosen the eraser
cap so much that it will never stay on. The eraser cap doesn't fasten securely
to the pencil, and it is very irritating to have to worry about it coming off
For writing I would rate it a 3/5, because it's cumbersome to write with the
guide pipe at halfway for increased stability. I use this to write
Chinese/Japanese every day also, and it performs decently.
My biggest complaint though is that it is uncomfortable to hold. For some
reason, my hand sweats noticeably more when using this pencil over others, this
is annoying! This pencil is also smaller than you would expect, and for my
average-sized American hands it was still too small to write with comfortably. I
would ONLY recommend this pencil if you have small hands!
