If I could have given no stars I would have. The first lot of cartridges I bought from here they didn't seem to last long and both the black and the colour wasn't as good quality as expected, also my printer was indicating the cartridge ink level was low. I emailed the company and was told that this would happen it's quite normal, so I just took that and carried on. I gave this company the benefit of the doubt and bought another set of cartridges but this time the cartridges didn't work at all the printer was indicating that there was no ink at all and even after doing a total maintenance clean on the printer still no luck, so I went direct to canon and bought ink from them that only cost me £4 more than off this site (so i was extremely happy) put the ones from canon in and they worked perfectly. So from now on I am only buying canon ink SO PLEASE PEOPLE DO NOT WAIST YOUR MONEY. In our small house hold of three the printer is used an average amount of time in case you wonder on the amount our printer is used.
