Because I have so pleasantly surprised and convinced these cartridges, I admit the first time an evaluation. Since 2years I print with HP original tanks were empty quickly from time to time. So I ventured "with some palpitation" this experiment. There were over Amazon a quick, well-packaged and complete delivery. The cartridges are transparent so that there is even an optical control of the filling. All cartridges were really XL-full! After I answered the message of my HP Photosmart B110 "non-HP cartridge installed" OK, my printer accepted the cartridges and prints now fortunately - also colored - how to it! The pressure-coverage, I could not check because I have only just begun with these tanks to print. Nevertheless, if the goods remain in their quality as, it is an alternative to the original - even considering the cost halving - fully recommended!
