Review on 💡 HP 645A C9730A Toner Cartridge - High-Quality Black Ink for Optimal Printing Performance by Paul Zimmer

Worked great - just like the original toner cartridge should! I couldn't be happier! I've tried several other non-OEM toner cartridges with mixed (usually bad) results. Sure, this toner cartridge costs more than a remanufactured/refilled cartridge, but it has given me several months of trouble-free service and I expect it will continue to do so for the life of the cartridge.
