Espectacular
I have tried over the years many non-manufacturer replacement toners for dozens of printers. And they rarely work out of the box. This one does for my older HP inkjet multifunction printer. the instructions were clear, and there were probably a half dozen flags and stickers and cards inviting me to contact their twenty four seven support if I had any issues. This was comforting, but to my surprise, no customer service contact was required.It just worked. Kudos to this seller.
