The inks work wonderfully with my Canon MG5250. Simply snap in and completed, are recognized immediately. From the life I would rate the Pripa inks to be identical to the original Canon. The colors differ very slightly from the original inks. However, this does not interfere further (I print mostly photos with the printer).
From me a strong buy recommendation. It would be desirable only if you could put together their own ink set (for example, would rather prefer two black inks have three yellow)?
Ink level gauge works. Where the Canon indicating quite early to an empty cartridge ... and then you can still print some pictures.
