I will never buy another HP product. It is corporate greed to put blocking security chip in toner cartridge. I own the printer. I'm entitled to put any brand of toner i wish.
Toner Cartridge works great. My only regret is the vast number of different cartridges with similar sizes, shapes and identifiers makes it error prone to select the correct cartridge. I don't mind the price except when you buy the wrong one and you don't realize it until it does not quite fit in the printer. At that point, it is not refundable.
