1.0 out of 5 stars Runs Out Way To Fast NOT WORTH THE MONEY, August 25, 2007

This review is from: HP 21 Ink Cartridge, 190 Page Yield, Black (Electronics)

I myself am having the same problem that alot of other reviewers are having with this product! While I am happy with the HP Printer itself, this #21 cartridge doesnt hold enough ink and runs out VERY FAST(mine ran out in two weeks). Keep in Mind that I only use the ink to print postage and I always use the fast draft which uses less ink and I STILL have to replace the cartridge frequently. I can only imagine if I used the normal print mode, I would be running to the store every other day to replace the cartridge. Of course most of us know that these companies dont make money on the actually printers, they make money on the ink! Anyway, I am going to try one of those refill kits and see if that cuts down on the cost!

In the past we had cartdriges with 25ml, now they give us a printer but recover the expenses with inks.

5.0 out of 5 stars Good Brand, Good Price, Good Quality, December 8, 2007

I have to disagree with people that think they aren't getting their money's worth on ink. I have an Officejet 4315 that I use to print several pages per week for school. I also own an Inkjet 697C. Yes, the 697 cartridges have twice as much ink, but they are also twice as expensive at around $25-30 each. I simply changed my default print setting to Draft, which prints 300 dpi, and it prints B&W text just as nicely as the Normal setting (600 dpi). You may not want to do this if you print work/professional graphics all the time, but I used the Draft setting on color for printouts for my Anatomy & Physiology II class last semester, which worked just fine. 1 black ink cartridge (HP 21) on the Draft setting will last me most of a school semester, printing 10 - 20 pages per week (of mostly text with a few graphics). I used 1 plus a partial color cartridge (HP 22) last semester.
