In the past, I've purchased generic cartridges and even refilled a few on my own but never with good results and in one case, I know it cost me a printer. Its just so easy to order authentic HP supplies on-line that its not worth the potential lost time, effort and equipment to do anything else.
Product was easy to order, price was fair. It came in quickly and was easy to change out and use. Haven't had it long enough to see how many pages I'll get out of it yet.
I do a lot of printing. All I've ever used is original HP ink for my printer. They are dependable and trustworthy. I spend a little more for quality of the name I know I can trust.
