I have bought this product for awhile. I like the longer life it gives me. The ink stays bold until the end. Love the bags for returning the empty jets. Also like the prompt shipping.
I've not loaded it into my printer, I just like having it ready for when I need it, but I have always been happy with HP printers and ink, so I know I will be happy this time, or if not, I am sure HP will take care of my issue.
I bought backup inks on-line because of sheltering in. The ink came on an envelope, not a box. The ink boxes were partially crushed, but I won't know if the cartridges will work until I need to replace the present cartridges.
