Review on 🖨️ HP 15X C7115X Black High Yield Toner Cartridge - Enhanced Performance for Exceptional Prints by Kevin Bigelow

Cartridge left dark horizontal streaks every 1.25 inches or so - 7 per side - also with dark side center. These dark areas had blurred boundaries. Overall experience is similar to several other reviews. The toner cartridge looked brand new, sealed in a bag, with full HP logo but in an old HP box. This box may have withstood temperatures other than those recommended by HP (the box says -20°C to 40°C). I bought it for $67 which is a lot more than many remanufactured cartridges but less than new HP cartridges. HP's website currently lists the 15x for $99 and the 15a for $89.
