I'm no ink expert, and haven't tried the more expensive ones, but this one is
just right. It is a dark black, and the price is right. Also the bottle comes
with a blotter tape and the curve inside of the bottle helps getting the last
drop. In other words, its great for the price!
The bad review is that often times, the nib is defective. The nib the came with
e+m nib holder was defective, this replacement nibs bag, had 3 defective out of
6. If you get a working one, then its good. It is very bendy and it has a nice
look to it. It holds a decent amount of ink.
The nib holder it great, it has a nice balance and feel to it. The nib the came
with it, was defective. The nib slit was not centered, making one of the tines
tip extremely pointy like a needle, picking up paper. Jetpens sent me some
replacements nibs, and out of the 6, 3 were defective like the one that came
with the nib. It was very nice for Jetpens to send me a few replacement nibs,
but the fault is at the manufacturer. I recommend buying the nib holder and
using a different nib.
