4.0 out of 5 stars good---but somewhat overpriced (three and one-half stars), June 28, 2008

The HP 21 inkjet cartridge is very light, easy to install and allows the printer to print out very good quality, durable black ink on the page. It stores for about a year after you buy it so if you want to stock up for your office or personal printing needs that's great! (It even comes with an expiration date!) HP also packs it well so that it is difficult for the cartridge to become damaged during transit.

One thing that I didn't like, however, is that the ink can go quickly. If you print a lot, you might even need to replace this cartridge every ten days or so. My needs are about 10 pages per week and I have to change the cartridge roughly every six to seven weeks. That's not good; although to be fair to this HP ink cartridge I am printing graphics.

As of the time that I am writing this, why don't we get a better discount for buying two cartridges? I notice the price to buy two is just slightly less than twice the cost of one of these HP 21 ink cartridges--but buying two should be cheaper still since you're buying two and not just one at a time; instead HP wants their customers to pay twice without giving them any discount or "price improvement." You might save a little over a dollar by buying this twinpack; but that's not much. There's just no discount nor is there any financial incentive to buy more than one at a time--and, as one reviewer notes, this is a disappointment.

Three and one-half stars for being great ink in easy to manage and install cartridges. It loses one and one-half stars for not lasting longer AND not giving customers a discount for buying more than one cartridge at a time.

If you really do not want to throw out your printer out every time it runs out of ink you cannot go wrong with this deal. The twin pack is a hair more than most dealers single packs, you have spare on hand, and you order half as often. Now if they had one for the color too, that would be perfect.

It seems like everyday, we are trting to find the best in inkjet cartridges these days. Although some are cheaper than others, like store brands, it is the quality that makes the difference. This 2 pack of HP 21 Black inkjet cartridges is easy to setup for your printer, and connects like a snap. These cartidges works very well with my printer. They are also compatable with the Deskjet 3900 series and other HP printers. I really recommend this 2 pack because it saves in money and in value for all your everyday printing needs.
