I bought it because it was claimed to be compatible with the HP 902/902XL. Also, it was a lot cheaper than HP's inkjet replacement. This is a correct statement. You get what you pay for. After trying multiple times to make copies on my printer after installing a replacement LD cartridge, it NEVER worked. I messed up a cartridge trying to get it to deliver ink to the specified reservoir/disc. I couldn't return it as I had already ruined it. It was just a waste of money. I will never buy an LD cartridge that says HP COMPATIBLE. It doesn't work like it should.
