Yes, I did get the official converter. I think it was a waste as it doesn't do anything aside from the not very useful screw-suction thing. Even when fully out the suction mechanism does take up space that could be ink volume and after the first disposable that came with it refills have come more often.

If I ever use a disposable cartridge again I'll try reusing it instead.

Refilling with a syringe is fairly easy. Lots of places sell blunt-tip syringes or you might be able to get away with insulin needles (I'm not sure -- pink tipped luers are the smallest I've ever used).

Do use luer-lock though, because the other kind of syringes suck. Just ask your local pharmacy -- they usually carry them and they can be used for all sorts of non-illicit-drug reasons.

In the US/Canada Lee Valley sells a set of blunt tip syringes for inks and glues.
