In terms of size, the cartridges fit well, the chip is detected, installation or replacement of the cartridge is the same as the original cartridges. High I mean a difference to the original ink to notice how very noticeable this difference is acceptable or should be every man for himself he entscheiden.Ob compatible cartridges instead of original cartridges course. For me, a cheap alternative in between (I print a lot), I switch repeatedly between the original cartridges and compatible. The printer makes it far with without any fuss or problems. The shipment was carried out really fast, ordered - and already there. Gladly again.
