So far this product has performed very well. All my printers are HP and this is the first time I've used someone else's brand. The specific printer that uses this product is an HP Color Laser Jet CP2025 and when I installed one of the cartridges I didn't even get a flash from the printer saying it was not a genuine HP product. I mainly use my printer for work, I print quite a bit, the cartridge lasted and I didn't get any error messages. I've only used one of the cartridges so far, but I'm happy with the result. This product is very good and since I installed it I have printed many books, registrations, withdrawals, records etc and it has worked beautifully. This product has saved me so much money and I will probably buy it again when my first purchase ends.
