I never bought compatible cartridges before those. I did not clog the nozzles and there was a lot of negative reviews on compatible cartridges. Until the day the manufacturer cartridges are past the 4 to 40 colors. I got tired of paying so much and especially make me have (empty ink indicated when he left, oddly 3 colors are completed at the same time, etc.). I tested these cartridges and no problems yet I do not often print. Quality is a little below that of the mark but at this price, there is no comparison.
