The HP 950XL 951XL Color Ink Cartridges C/M/Y Combo Pack (F6V12FN#140) are great. My wife is a school teacher and prints a lot at home on our HP office jet 8600. With these XL 950/951 cartridges the ink sems to last for months without having to be replaced. I also have not had any problem with the ink heads clogging up. I would recomrnd the xl cartridges because for the price diffrence you get a lot more prints for your money. I only use the HP OEM cartridges in my HP printers because I had had problems in the past with non OEM ink.
The ink cartridges work great they are a little tricky to put in to printer but once i got first one in it was easy. The black lasts longer than the color ones and will still print after printer tells me it is low or empty. They give a good color no matter what i am printing. Even pictures come out good quality coverage and color. I have used the black extra long one but only the the regular color ones i want to try the color extra long ones next time. I only use hp ink cartridges they work best with this printer.
I purchased a H P 950 XL 951 Color Ink cartridges Combo Pack for my H P Office Jet Pro 8600 Premium Printer. I buy the 950 XL cartridge because it contains a larger amount of ink.. The quantity of ink in the color cartridges are the same in all the packages. This package deal is a good buy and then I have the cartridges on hand when the particular color or black are depleted. I get good quality color on prints of my photographs and posters. The photographs keep their color when displayed and exposed to light.
I just recently bought a new HP 8610 printer. These replacement cartridges area as billed. They last a lot longer than other that I have tried and the color is great!
I have had 2 very good printers both from HP and love them.... The ink is great I have had absolutely NO PROBLEMS with it. The colors are vibrant and black is ... well black.
I have tried the refill kits in the past but have found them messy and do not give near the amount of pages promised.....Just us the HP cartridges in my printer and it is about 4 years old works as good as new.
