We use them in a corporate environment with desktop printers and non-manufacturer managed devices (automatic toner) and they are great value for money. For semi-regular printing from desktop lasers, the price is unbeatable compared to HP cartridges. That being said I only buy remanufactured cartridges for cartridges that don't require a chip, removing the old one and sticking it to a secondary cartridge doesn't always work.
