After about 600 prints, the problems started, while it still has 67% the prints are very bad. I changed the toner and it prints fine (with so few prints I thought the drum was the problem but it was clearly the toner). It was obvious as soon as I opened the package that it wouldn't be okay, it had scratches on the plastic exterior and the screws are "eaten" from unscrewing, obviously for refilling. Several times graphite came out in the prints. Conclusion: 9-10 euros (purchase at 9.90) for 600 prints, no, it's not worth it at all.
