The most annoying thing is that you end the cartridge then thinks that it will probably have a reason that Canon makes the cartridge unduruchsichtig. It is known that the printer does not measure the true yes ink content (rest), but at most the print job and thus the likely consumption.
In klarsichPatronen anyway notice that the ink flow - depending on the manufacturer - half full one is still 1-2 mm high gesÃĪttgit at the end of cartridge life time.
Conclusion: good value does not fit. Only an advantage one has (so far): the finger on the original product remains clean ... at the compatible often gets oneself dirty fingers or as happened to me yesterday the documents dirty on the desk by Spitzer. That's to be expected at the latest when the seller says that the cartridge is full than the original.
To that extent, a compatible cartridges at the end are expensive ....
