Good but not enough

Comments about HP 21 (C9508FN) (C9508BN) Black Inkjet Cartridges Dual Pack:

We previously reviewed this product as being a great quality ink; however, it comes in a package that runs out far too soon for the price point these cartridges demand. Our rating of not recommending to a friend is based on the premise that though this is a great ink that produces outstanding print quality, it is far too costly in it's present format.

        Excellent HP Genuine Ink.

        Comments about HP 21 (C9508FN) (C9508BN) Black Inkjet Cartridges Dual Pack:

        Hewlett Packard Ink is the most reliable, best quality, looks the best, and maintains these attributes over YEARS. I started scrap booking back when it first came out - guessing almost 20 years ago. My scrapbooks I made back then with printed graphic using Hewlett Packard Inks, has held up better than some of my photos have. They are inside acid-free scrapbooks, and the graphics are as sharp as the day I printed them off the printer. THAT alone demonstrates the HIGH QUALITY Hewlett Packard inks are. I will NEVER change using HP inks. I have read photos generally last approximately 100 years if kept in pristine condition. The graphics I printed and that are in my scrapbooks from 20 years ago look as if I just printed them off the computer today. I will always stay with HP inks.

        I like to use the HP brand ink because I find it consistently performs without problems. It may be pricier than the generics, but you get what you pay for. With Staples recycling and coupons, you can save money!

        HP 21 Black Ink!

        Verified Buyer

        Comments about HP 21 (C9508FN) (C9508BN) Black Inkjet Cartridges Dual Pack:

        This product is a great value for the money! It's long lasting and has bright vivid crisp black. I've tried the after market inks and nothing beats the manufacturers original! Having it delivered at no extra charge by Staples makes it the most convenient way to keep my printer up and running smoothly for all my business needs.
        I will continue to use the HP 21 original black ink cartridge for it's value, performance and convenience! I always bring my used cartridges in for Staples Rewards credit too!

        I like buying the twin pack or quadruple pack because in the long run it saves money. The ink lasts a long time for being such a little cartridge

        These work great in my printer. The customer service was above and beyond the call, staples is my go to store for business supplies. The store makes finding the ink I need for my business easy to find and always has what I need in stock. It is a pleasure to go in and do business with staples.
