This was my first toner change since I bought a printer with an original branded cartridge. It was pretty easy to install and has worked great so far. The only difference I've noticed is a slightly louder noise just before it starts printing (as it's warming up I think) compared to the original brand toner that was in the printer before. Not loud enough to wake the dead, but a little louder than the original so nothing to complain about. Can't comment on durability as it was only installed a few days ago so time will tell.
