This is a great refill for the variety of pens that it fits (not just Fisher
pens). The ink delivery is smooth and fairly consistent but it does glob a
little bit once in a while if you do not use it often.
This is a great pen for anyone who wants a smooth ball point that is pretty
durable. The grip is comfortable and the fact that it can write on almost
anything in any situation is pretty cool even though most of the time you will
never need those extra features. The reason I give it a 4 star is because it
leaves somethings to be desired in the clip department, and it is as if Uni
designed a rugged pen but forgot the clip. The clip is very flimsy feeling and
is not something that I would trust in the pocket. Also, the ink in this pen
seems to go by fairly quickly so it would probably be good to stock up on ink
when ordering the pen.
I have the 1.1mm version of this pencil and it is great as a general writer and
for use as a pencil for chemistry because you can more clearly see what is being
converted by using the red. The pencil is very good quality and feels like it
will last for a very long time. I would definitely recommend this to anyone
that needs an all purpose pencil and does not want to switch to a different pen
or pencil to mark in a different color.
