This ink seems to work properly in my printer, however, HP set up a warning that if I did not utilize their ink cartridges they would not be responsible if I had problems. So far, so good.

Bought for HP 8600 Premium. At first, HP recognized as non-HP ink cartridge. A message then said HP not responsible for any mechanical problems due to non-HP ink. After a few prints, the message prompt went away and the printer recognized ink - the fill meter reset to full. Printer is otherwise ok. On 'normal' quality, there are a few lines of black text about the page that have a line in them, or what appears to be a digital smudge. I cleaned the print heads and did a 'deeper' clean via the Printer. They temporarily went away but came back. NOTE, we never had a single print quality issue with the HP ink, from Draft through Best quality. When printing formal hard copies, I recommend you use Best print quality to avoid any discrepancy in ink/printing quality. Otherwise, this ink seems to do the trick at a fraction of the price.

Great quality product, came on time and was well packaged. When dealing with re-manufactured ink I worry about leakages in transit and at time delivery, but mine came in good as new. Fitting the cartridges did take some effort and a good deal of maneuvering but nothing that could make me resent it considering the affordable price and the excellent output I got. The printer recognized the cartridges easily and so far I have printed over 100 pages, around 20 have been full colored ones. The color quality has remained consistent so far. The colors come out just like those from HP ink and it costs just half of the cost – now that is what I would consider a good bargain. Would not hesitate to buy it again when I have finished the current set. Recommended.

The blue (cyan) cartridge repeatedly indicated it is broken or damaged on my printer and therefore none of the cartridges will work. Fortunately my old cyan cartridge had some ink left and I could get the printer to work.

When it came time to change ink, one of the crartidges wounldnt load because it had a broken tab.

Been using this ink cartridge for a few days now -- so far, it has been a five star experience: * print quality was comparable to HP's * ink cartridge casings looked well built * saved a lot of money (more than half HP's prices!) Definitely a recommended buy if you consider what we've received here for the amount of money spent!

DO NOT BUY THESE...THEY ARE NOT COMPATABLE WITH HP PRINTERS!!!!!!!!!!!

Fantastic Replacement Cartridges for my printer...highly recommended, and I will be buying again!

This was a great buy and I will be buying them again.

These were NOT compatible with my HP Officejet Pro 8600--despite claims otherwise. The printer would not recognize them as full and I was unable to print. Was a waste of money.

I did not realize these were after market cartridges. My printer said the ink cartridge was defective. I had to go buy a real HP cartridge to get the printer working. Will not buy these again.

It is not the best ink, but it is OK for the price.

Aftermarket cartridges are incompatible with my HP 8630 OfficeJet Pro printer. Constant error messages relating to damaged cartridge(s). This is the second set I purchased with same result.

It did not work with the printer but I got my money back

two of the cartridges had leaked all over their packaging. DO NOT RECOMMEND,

The price was great! Too good to be true! My printer will not work with this product! Very disappointed!!!

My printer completely froze and would not work with the cartridges.

Was not HP approved ink and would void manufacture warranty.

Not good failed after only a few prints, will not reset

Works just fine and price is much lower!
