Can't share any positive experience with inkjet refills. I print mostly in 
black and white on a laser printer. That being said, I can share this:

-Professional refill shops use steam cleaners like the Scunci ones to clean 
the cartridges. Probably would improve performance/durability.
-I believe that the print heads include a "heating element" of some sort 
that dries the ink on the paper. However, if you let the cartridge run dry, 
it will (perhaps permanently) clog the inkjets, so you don't want to let the 
cartridges run completely dry.

Hopefully that will help some.

I have refilled two different types of HP cartridges.  I like HP
printers very much.  The printers, and the PSCs, at least, (Printer
Scanner Copier) work well with GNU/Linux.  Very well.  The large
number of HP cartridge models makes it unwise to generalize; however,
I have had really excellent luck filling Cartridge number 56, and
color cartridge 57, with Inktek kits. I have refilled an inktek
refurbed 56 at least 10 times, with quality not diminished to a
noticeable (by me) level.   I also tried to refill an earlier type of
cartridge, for the Deskjet 932C, that had already dried out.  I didn't
have much luck, but I think the cartridge was bad or else there are
two subtypes that look identical with different inks, so maybe I got
the wrong ink.  I was able to refill the #56 cartridge several times
with the kit for the 932AC (don't remember the number of the
cartridge).

Earlier on, in about 1992, I tried to refill black HP cartridges for
the HP portable deskjet---a standard cartridge for that time, the
number of which I have forgotten.  I was able to refill using a kit
from computer friends, but after two refills, the quality was
completely unacceptable.

I think the newer inks and kits are much better.  At least my
experience is fantastic with the Inktek kits.  The #56 kit (black) is
10.00 if you look around on line, and I get four good refills out of
it.
