I haven't needed to use them yet. I'm sure they will perform well, as any HP product I've owned has. I think "enjoying" printer ink is a little over the top. Don't you?
Ok, I'll admit it. In the 20 years I've had my faithful HP Officejet printer, I have tried to use cheaper ink cartridges from off brand suppliers. I've tried the refillable ones too.
I came back to HP cartridges because they give me everything I want from a print job. Clear, crisp, legible. Ok, they're a bit more $$ but I can rely on them!
