Our printer had long since run out of ink and we were squeezing every penny because OEM inks were so expensive. Found this kit and thought wow this should be for every colour, no you get all four toner cartridges for less than the cost of hp black toner alone. We have used the printer many times since replacing the cartridge and have had no complaints to date. The print is crisp and clear as expected. No complaints. Very important. Can't comment on durability yet as it's only been a month.
