I have ordered "re-filled" printer cartridges in the past (albeit from other sources) so I expected the great results that I had experienced before. Not to be! The B&W were fine (checked out all three) but the COLOR cartridges were not - I had three of those also and none of them worked. You are sending out replacements - your Customer Service was excellent - but it remains to be seen if the replacement cartridges will work or not - if not, I won't go for more replaceents...I will expect a refund. I do appreciate your prompt attention to my concerns...thank you.
