I bought a refill kit for a basic black HP cartridge. The first time I did it, it worked beautifully, with nary a spill, and the cartridge performed as well as it did when new.

When I tried to refill it the second time, it was a complete, leaking disaster.

Regarding commercially recycled cartridges such as those you get at Office Max, I used them a couple of times in a fax machine at work (well, when I still had a job, that is), and I found that, while they performed okay, they do not have very much ink in them.
