I purchased these cartridges from Silver Trade before about half a year for my Canon Pixma MP620 and am very satisfied. I have now replaced all the cartridges from the original cartridges contained after purchasing the printer and can say this is not to distinguish the quality of the images and text printouts of the original Canon cartridges. All cartridges have been detected immediately, light up red when eingesezt and are compatible with the electronic level indicator. They are also economical, provided me with more color than the originals. Ordering the same cartridges carried the same great price - performance ratio as before.
