There was a quick delivery. The toner fits perfectly into my printer (HL-5340 D). It has been my experience in the private and Job, that there is toner from alternative manufacturers who do not fit perfectly, so that the front cover does not close properly. That's not the case here.
It will be printed absolutely clean. I notice no qualitative difference to the original toner, which comes bundled with the printer.
It's still a bit too early to present a final outcome, but so far I'm very pleased with the toner.
