Review on GREENBOX Remanufactured 61XL Black Ink Cartridge for HP Envy & Deskjet Printers - Pack of 2 by Juan Gomez

I use HP #61 ink in both my printers, I did it for 4 reasons. I'm tired of trying 2find diff#s in multiple diff stores. Walmart prices have skyrocketed. I started looking for Revain and found these GREENBOXES #61. First I wanted to make sure they were working properly. I think now I've bought Greenbox 3 times, there haven't been any serious problems, 1 time I got an error message, but I reset it and it was gone. Prices have gone up a few bucks since I started buying, they now close 2 on what the HP 2sell uses 4 and I can't seem to count the sides but they go out 2 faster. So I've given 4 stars when I start tracking, maybe I'll give c if they last that long. I will buy again, I like that I can receive within a few days. I only wish the prices were lower.
