HP 21 Black injet cartridge
I wasn't really that impressed with this item. The cartridge ran out of ink within a couple of weeks and I don't do that much printing.

about time
I didn't think I was ever going to get this. Next time I'll go to Wal-mart.......

HP does great
I have been sold on the Amazon system for getting my printer supplies. I consistently get a low price, free shipping and keep the office running. Living overseas and finding excellent supplies quickly can be a challenge. Amazon and HP do us well.

extremely happy!
I chose to buy this item in conjunction with two others, on a hunch. The waiting for arrival was short, but seemingly long, only to me. I was anxious to try it out because an ex-employer swears by the equipment in his office. Now I can see why, its easy to maintain, reasonably priced, and easy to find. I would definitely recommend this product to all with a five star rating. I am 100% satisfied with my purchase.

I purchased this ink cartridge as a package of 2... it was a better per unit price. It arrived quickly and was packaged well.
