I waited a long time before deciding to buy this, mostly because of the price
relative to other style fit bodies and because of the previous review about not
being able to see the color of the ink barrels. I'm glad I ended up buying it.
You can definitely see which ink you're using through the clear window, even if
the ink runs low, because the refills themselves have color printed on them that
reaches to the level of the window. I personally found the weight to be just
right, and I don't think that it looks or feels very cheap. Also, one of the
things I didn't like about the design in the picture is the gold rings on the
body. However, that's actually just part of a sticker, so the body is just one
solid color, which I think looks much nicer, especially for the other colors
that don't match so well with gold.
My one gripe with this body is its mechanism. The top portion that twists to
select the cartridge doesn't turn 360 deg, which means that if you want to go
from color A to color C, you have to go through B (if that makes any sense).
Compare to other refills, in which you you can just quickly select the color.
Another thing about the mechanism is that in order to retract the cartridge, you
twist the barrel to a position between that of 2 cartridges, which is actually
not a very stable position. I can imagine that if the pen gets thrown in a bag,
the barrel can easily get rotated so that one of the refills gets selected,
ruining the refill and getting ink all over my bag.
