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

I use HP#61 ink in both of my printers, I did it for the 4th reason. 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 are now closing 2 which uses HP 2sell 4 and I don't seem to be counting the pages but they are closing 2 quicker. 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.
