Hello There, I was skeptical at first because I had already tried several cartridges of other providers and this did not work. The cartridges were delivered quite fast but for five euros Shipping dermasen Miserabel packed and taped unloving but oh well. Cartridge unpacked from the printer, a cleaning operation and everything went like clockwork. I use a Brother MFC J470 DW. Four stars otherwise it would clearly five stars only because of the punk packaging.
