Two of the compatable Canon cartridges leaked. Not had any problems with dozen or so CLI 521's purchased before.
E.mailed Stinkyink. Immediateely replaced cartridges with no quibble. Excellent service. Excellentt compatable 'chipped' cartridges . Highly recommend Stinkyink and compatable Canon cartridges .


I have been using these compatible cartridges for my Canon MP560 now for a number of years obtained from Stinkyink and they have been excellent


Stinky Ink continues its excellent customer service. The latest order was delivered promptly and the compatible cartridge works just fine in my Canon printer.
Highly recommended.


Once again excellent and prompt service.


these inks are perfect for my Epson printer. the print quality is good and the cartridges are easy to install. the service from stinkyink.com is first class.


Working OK. This cartridge was to replace one which came as part of a full colour set. The remaining ones still show full, but the Magenta one emptied!!!

I do not understand how this happens, I have had the problem before from Stinyink cartridges.

Hi Barrie,

Sorry, the magenta cartridge read as empty. This shouldn't happen so I've arranged for a replacement magenta ink cartridge to be posted out for you today. This should reach you by Monday.

If there's anything else I can help you with please let me know.

Kind Regards,
