Why would I want to use any other ink when I know this is always top quality. My late husband told me "use quality and you will never be disappointed." We have used HP products since 1985. Why change something that is not broken.
As a small business owner I can't have downtime with ink or printer worries. My HP Officejet Pro 8600 combined with the 950 XL and 951 cartridges are a winning combination. The printing quality is excellent and I usually get about a month out of the cartridges which is surprising since as a distributor of architectural products I'm constantly printing specifications spreadsheets drawings and quotations. Although the ink cartridges are not inexpensive when I recycle the empties at my local Staples my reward total is typically $20 or more a month.
