Unbeatable. Frankly I am stunned by the saving. Basically a good rate on an official minimum cartridge costs 10 euros (20 euros in stores ?? !!) So here the saving is 30 x 10 to 20 = 280 euros. Seriously, cartridges work. I do not know if they can damage the printer force but in any case I print my pictures correctly and cartridges are recognized. In short, 280 euros.
