I am unsure what to make of this product. Price and print quality are great. But you need patience. Every now and then a cartridge is not recognized, you have to change it (annoying when it is half full yet). Makes a cartridge change and sometimes tens of cleaning cycles until all print again. Occasionally goes into this process then one other cartridge empty, so you have to make the exchange and further purification processes.
After I have used for testing purposes the original cartridges, but I must say: The quality of these cartridges is great and the value for money unbeatable better.
