I have long used the original Epson ink cartridges, and I have never been disappointed.
By cons I wanted to try once supposedly compatible, this was the cat.
The black cartridge drooled sprinkling my paper sheets of black ink, and when I tried the yellow printer stopped without warning. I thought then that I had screwed up my epson stylus photo R220, but by going to see on the site epson europe I learned that he had to wait several hours in case of lock to get it going again even with cartridges originally replaced.
I left overnight and restarted in the morning .... and good surprise, she left without problem .... with the original cartridges.
So yes packs 20 euros I've had enough, and I understand that the compatible cartridges are compatible only half, so they ended up in the trash.
