I have been using a 7800 and a 9800 for years with some refillable cartridges and ink I got form a different company. I was very nervous about putting brand new cartridges for my "just released" 9890 as it was so new it was largely untested, but the people at
Efillink.comdid a great job getting me exactly the product that was needed to save THOUSANDS on ink. When the cartridges showed up I was AMAZED. They were so much better quality and craftsmanship then the ones I had been using it was ridiculous. The quality of the plastic, the joints, the internal structure, the few moving parts, the chip, and right down to the innovative little tip that made priming the cartridges a SNAP. Plus the chip resetter that was included had a removable foot that fit exactly to the cartridge so no more getting down and squinting just slap it on there and go! I was so happy with my purchase I felt compelled to write this review and would recommend anyone IMMEDIATELY switch to an ink system from Efill as you will pay for your printer in no time and with no worries. Thank you Efillink!!!
