I WAS SUPRISED THAT THE BLACK PRINT USED ALL THE COLORS IN THE PACKAGE SO WHEN THE INK WAS ALL USED IT WAS NECESSARY TO REPLACE THE ENTIRE PACKAGE NOT JUST THE BLACK UNIT. SINCE I DO MOSTLY BLACK PRINTING IT MAKE THE PACKAGE LAST LONGER. I STILL PRINT THE OCCASIONAL COLOR COPY SO THIS IS A GOOD COMPROMISE TO GET BOTH COLOR AND BLACK. NO COMPLAINS THIS IS AN EXCELLENT USE OF THE COMBO PACKAGE. THE COMBINATION PACKAGE IS A GOOD VALUE RATHER THAN BUYING EACH PACKAGE SEPARATELY. EXCELLENT MARKETING. I RECOMMEND THIS PACKAGE AS AN EXCELLENT VALUE TO THE VOLUME USER.
i have one HP printer and may add another. Both Printers use the same Ink and the ink seems to last for awhile. The quality of pictures and word documents are very clear and crisp.
I use these ink cartirdges with my HP Officejet Pro 6000. The color ink has vibrant colors and brings forth very clear and neat presentations. I print alot of pictures and information from online sources and the ink has never let me down. I prurchased my HP Officejet in Otober 2013. I recently replaced my ink supply in November 2014. That's what I call value! No other ink wells for my previous printers can measure up to the HP950XL/951 High Yield Black & Color Ink.. It's worth the price.
