Had one working laserjet toner cartridge that worked out of 4, and it requires occasionally reseating it to keep working, and ordered approx 12 cartridges for friends and neighbors and so far none have worked at all, including a color cartridge leaking black ink all over the printer and the rest not working at all or not even being detected. The little money you pay for the products will go straight in the garbage. They do not respond to emails requests for defective products or refunds for unopened products either.
