the cartridges were delivered very quickly and well packed. Each cartridge was filled properly and individually welded.
The film was removed and the cartridge inserted into the printer - instantly cartridges were detected (the fuel gauge was also correct) and it could be easily printed in an acceptable print quality. A great print quality obtained in my opinion, only with good laser beam printers (but only incidentally).
Individually, I could not use this cartridge, ie they had to all be used together in order to work,
For other manufacturers can also eg Black (BK), black (PGBK), yellow (Y) from manufacturer A and magenta (M), cyan (C) from manufacturer B integrated.
However, this was not a problem for me.
