For several years I have my printer, I am faithful to Amazon and HP cartridges 301 (I regularly order in black and colors). They are great these cartridges: very easy to change (and even "emergency" because it is always in such moments that your printer tells you that it is necessary to change the cartridge), they last a long time, several months at home ( Finally, it is following the use made of it). Thank you Amazon, because they really are cheaper on the website than in stores! I remain a fan!
