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

Insert a new one in the printer and horizontal black streaks appear on the Pages. It didn't happen until I put this new cartridge in. As I always have at least one new cartridge "in reserve" when I run out of toner, this new toner was actually ordered months ago so it doesn't look like I can return it. This makes me doubt whether I should order another cartridge of this brand. UPDATE: Apparently V4INK saw my review here and immediately emailed me to apologize for my issue and quickly sent me a new toner cartridge. The replacement cartridge works great and WOW what customer service!
