I am a bit wary when it comes to compatible replacements for genuine parts. This worked well and improved print quality (it had an old, worn drum that smeared the pages). The only issue I had was that the release button was a bit loose so I had to press it when I installed the toner cartridge. As I said, it worked and I'm currently using it, just don't know how many times I can press the release button before it breaks. Regardless, the cost is worth it. Delivered quickly.
