These cartridges were the replacement for the original cartridges when printer was bought and installed. It will be of interest to see how long these last. Installing the new cartridges is as easy as it can get. Push in to release push new ones in to set. I'm still amazed at how much printer ink costs! Being someone that is employed in a related chemical manufacturing I know that these colors don't cost this much! It would be great if someone made refills that eliminate replacing an entire cartridge unit unnecessary.
My work place has used this brand and type of ink for over a year. So far there has been no complaints. The ink has nice bright colors. Since it is a work place as you would guess a lot of ink is used in the running of the business. This product was the best buy (two were purchased) especially with the coupons that was included in emails. I really liked the buy one get one half off coupon on HP inks. Yes I would buy this exact product again and yes I would very much recommend this product to someone else.
I am a photographic book publisher. My books are mainly photos. I use the HP XL ink's in my HP 8600 printer. I get many photos from one cartridge which I need because of the volume of printing that I do.
