hp is effectively stealing from me. Last cartridge set I purchased did not work. After some research I learned it was because the previous cartridge set I purchased for Amazon were “Z20” region cartridges. I brought them from the same page you are reading now. Since then, hp updated the firmware on the Officejet pro 8600 printer I own so that it will not accept a different cartridge. But, now the only cartridge type you can buy from anyone in the US is a “Z10” version. So, my printer now gives the “Incompatible ink cartridge” error message which also LOCKS the printer and prevents it from printing. In their zeal to prevent knock offs and clones,they effectively also caused my printer from printing. I have been on tech support for 90 minutes now with no resolution, except “we’ll, we no longer support that printer do your only option is to buy a new one.” Where did I go wrong. I asked the Tech Support person and they said I did nothing wrong. The Z20 cartridge worked without any updates or configurations. Did I know I was effectively obsoleting my printer by updating the firmware now that only the Z10s are available? Of course not. This is stealing - hp stole my ability to print. And they suggest I can buy a new printer? I am angry. I will call Amazon and them them about this experience, to which they are partially complicit. I may do more. Bad Bad Bad

Yup - its ink. Expensive but it works. If it were cheaper I would have given it 5 stars. I suppose HP has to make its money somehow though since they basically give their printers away.

Printing quality good but expensive!

Ive been buying HP cartridges because I know I can depend on them.

Never have a problem

After the second cartriages gave me that incompatible message, I started looking into it and reading the reviews. All I have to say is AMAZON: youre better than this!!

expensive everywhere and dont last long enough

Good price for the product.

Quality product for my printer

I would like to return this cartridge. It does not FIT!
