Review on V4INK Compatible 26A Toner Cartridge - Black Ink Replacement for HP Pro M402n M426 Printer by Jeff Bremmer

These are the only ink cartridges we order for the office. We used to buy branded products, but they were prohibitively expensive. We ordered them on a whim and have no regrets. We currently have 6 HP desktop printers using these cartridges and have never had a problem. Surprisingly, we've only been using this cartridge for the third year. I don't know why we didn't switch sooner. We could save hundreds of dollars.
