Query: No instructions and doesn't work for my printer

I can't say anything about the quality of the ink because I couldn't print with my printer (which takes HP564 cartridges.) The details about the product say that it will work with most 4 color cartridges but doesn't actually say which printers it does and does not work with. Furthermore there are no links to the website where you can find out whether it works until after you've already purchased the kit. The kit includes a piece of paper with a link but no actual instructions for refilling. The website itself also doesn't seem to work very well. Overall it's a disappointing purchase and I plan to send the kit back.
