Refill / Rebuild? So far: No, thank you - but now ...

I have to - to purchase (and now even after prolonged use) state clearly once again:
These "compatible" ink cartridges are great! I use them in a Brother MFC-5890CN and am thrilled. Finally I no longer start to sweat when my son says to me again: "Papa, I printed the Internet!"

I have long been on the manufacturer's original cartridges (then "Canon"), because my fear, the printer or the print heads with Refill / Rebuild cartridges damaging familiar, was just too big. But after I found the printer even with the exclusive use of original cartridges with a defect (printer only showed an error code) out of warranty beyond repair economically (= rubbish bin) I thought to myself, then to yet the next printer be operated economically at least in the 1-2 years of its existence. What I have money for original cartridges (Canon then up to 50 euro for 4 pieces - you know yes the prices!) "Kicked out of the window"? It's with these cartridges from NTT past - now the printer is actually used once uninhibited, it was unthinkable before ... because you have considered three times, if you now print out something, or rather not.

Before it is too exaggerated here - a small gripe there are: Although the cartridges SUPER-fit, no problems at the onset - BUT: to be One should not be frightened, the sealing of the cartridge seems firmer than in original cartridges, the means "press fixed" Something you have to the cartridge when inserting already ... (it cracks unpleasant) - but now I have several colors used (. including in the mix with the still partly prev original cartridges) - there is in my opinion no color u. Quality losses. I have a large (color) print job first started yet with original cartridges and replaces them in the course of the print job to the NTT-cartridges - What can I say: no visible difference in color representation between the first and last pages of this order.
I use the cartridges now for about 3 months, and of course I can not tell if the ink (permanent) harm the print head or not after this time? Definitely I can say that so far is running my printer with no problems, the ink level indicator works exactly as with original cartridges and the print image is so far always in order (no stripes or dried paints, etc.), so I speak from my view and in my experience a very strong buy recommendation from!
