This is the ideal pen for taking complicated notes. I can color code as much as
I want without having my desk covered in a bunch of different pens. Not only are
5 color notes easier to read, but they look very impressive at a glance. The
cartridges fit the end of the pen very snugly, so there isn't any annoying
looseness, which is a problem on those common Bic multi-pens. Bringing out a
different color doesn't take much force and isn't loud, so you won't be
disturbing people next to you. I also sometimes have classmates tell me how cool
my pen is, which is nice.
There are some minor downsides, however. Sometimes, when switching to an
adjacent color, the pen will jam. To un-jam it, you just have to click a color
on the opposite side. The joints where the sections of the pen meet are very
weak, so this pen will have to stay in a sturdy pouch or bag next to other
pens/pencils. If you put it in a pants pocket it will surely break. Also, the
ball on the 0.3mm cartridges is very small. Thus, writing at small angles can
sometimes be scratchy.
