Review on 🖨️ E-Z Ink (TM) Compatible Ink Cartridge Set for HP 920XL 920 Officejet Printers - 6500, 6500A, 6000, 7000, 7500, 7500A E709 (2 Black, 1 Cyan, 1 Magenta, 1 Yellow, 5 Pack) by Paul Ruberto

Nice instruction warning you not to squeeze the cartridge and I obviously did and a bunch of black ink spilled on the printer and on my tiled floor thankfully it was over Porcelain tiles and not in the joints the seam or I would be screwed. Cleaned ceramic tiles with alcohol. Not sure about black but the color cartridges are clear so you can see ink levels which is good but these cartridges are really thin walled and every time you turn on the printer it says you have Counterpit ink that is not illegal in printers should be subject to federal law, but these printers should be prohibited from posting messages like this that require you to press confirm. I'm sure that's why some people only buy original and expensive inks.
