... But you still have to be careful when höllsich cartridge change. I have not exactly kept it and there is rausgeloffen above what. When I tried to wipe it off with the Zewa, has the same pretty much sucked me out of the ink inside ... now I'm smarter. So if you subtract the film, just keep!
The original cartridges I had no such problem.
Otherwise, the quality is actually, the installation and compatibility were as it should be, everything went smoothly and the price is of course unbeatable.
