Got my lexmark ink refilled the other day. Wait time was less than 5 minutes and cost was 1⁄3 of what I would pay for a new cartridge ! This is only the second time I have gotten a cartridge refilled. Previous refill was done at Walgreens. It took longer and my black ink was not a true black(more like grey) I just tried the ink from cartridge world and it works good. If after a few days of use there are any unfavourable developments, I will update. Otherwise all looks well and I would recommend this place to anyone. Summary of refilling your ink: Good for the environment and good for the wallet. Note: My printer does not recognize refill cartridges as a new/full cartridge, and I guess this is the manufacturers way of having you avoid filling your cartridges. In any case, I just trust my vision to tell me when I am running low on ink(faded prints) Besides my orginal ink cartridge had begun to sound the low ink alarms at least a month before I ran out.
