So far so good. I've been using it for a couple weeks now and at first, my printer did not accept the cartridge. I pulled it out and installed it again and this time it worked fine. The print quality seems fine and It was about $50 cheaper than buying an original Kyocera toner. TIP: always have the toner facing upright. I made the mistake of not paying attention to how I put it on my desk once I had the cartridge open and unpacked. I ended up with a small mountain of toner tipped out of the cartridge and I had a small mess on my desk to clean. Not sure if this would have happened to an original Kyocera brand toner, but I think I've just learned my lesson either way.
