Doesn't last as long as other toner only 8,700 on average. We started keeping count and were surprised. Also Can you make a high yield for M601. Our firm only buys OEM, so we are stuck with this cartridge or throwout our M601 Laserjet
HP printers are the only kinds I'll buy because they're durable, tough, long lasting, efficient and economical, and so are their toners. I've tried buying refurbished cartridges from major office stores and they had to be replaced very shortly thereafter. I love HP products and toners and never have to be concerned because I know I'll never be let down. Thank you HP!!!
