Review on Miss Deer Compatible 934 935 Ink Cartridges for HP 934XL 935XL Printers - Officejet 6812 6815 6820 6825 Officejet Pro 6230 6830 6835 (1 Black, 1 Cyan, 1 Magenta, 1 Yellow) 4 Pack by Nathan Skipper

I am very satisfied with these cartridges. They installed easily and had no issues because they weren't HP products (there was a popup notification I just clicked on). - The price is acceptable. After all, ink cartridges are made of plastic and ink. There is absolutely no reason why an "original" or branded product should be so expensive. These Miss Deer cartridges are a quality product at a reasonable price. After seeing how well they worked I ordered a second set to have on hand when the first set ran out. That's a good find. Highly recommended.
