MicroJet Compatible Refillable Cartridges Replacement for HP 950 HP 950XL HP 951 HP 951XL Cartridge For Officejet Pro 8100 8600 251 276

Suspect HP firmware updates killed printer's ability to use these cartridges. I traded HP for Epson Ecotank which carries enough ink in its tanks for 10 or 15 of these cartridges, very happy with Epson, will never buy an HP product again.

This product is total junk !! I removed my HP cartridges, installed all your cartridges with air plugs removed, printer did not recognized your cartridges, told me I needed to install ink cartridges and would not print at all. Put back my HP cartridges back in and printer worked fine. Also they show cartridges labeled as XL, but the ones you get are not. This does not matter because they just do not work. Do not waste your time or money on it !!

They fit the printer, but I find the color does not stay bright with multiple use. I have to clean the printer heads more to get the color back which means I use more ink. I hope this gets better. Delivered on time without issue

Word of caution here. We've used refillable cartridges for an epson printer for years with no problem. When it died we got the HP8610. CIS Inks jumped through hoops to get us a working set of cartridges and we finally got all of them except for the yellow cartridge to work.* We ordered another set from a different seller to see if we could get a full working set and put in the yellow cartridge right away. Couldn't get the printer to see the cartridge no matter what we did. So maybe the problem is the chip for that cartridge. Doesn't seem to be a seller issue. Although I'm surprised anyone wants to mess with selling these. We returned the cartridge set. No problem.We're buying an HP yellow cartridge as needed and then refilling the others. Still, this printer really does seem to guzzle ink. If we were sure going to an Epson would allow us to use refillable cartridges again, we'd scrap this printer. Or if someone knows how to get a working set?* To get the cartridges to work, we found you have to switch out from an HP cartridge before you get a low ink message. If the refillable cartridge gets too low, we put in an old HP cartridge, reset the printer and then switch with a refilled cartridge.

I have hp pro 8600 but it had run off ink. I checked the price for the full seat of ink cartridges on many places but it was very expensive. I found this product on amazone and the price was really acceptable. I bought it and it worked well with my printer. I will not worry about the ink again since I install this product on my printer. Thanks amazone for this great deal.

Won't work on my printer model.

Exactly as described. Very easy to install.

So far I have only used the black cartridge, it worked for a little while but then quit working. I've tried cleaning the print heads multiple times to no avail. Unfortunately, I didn't find this out soon enough and I have passed the return date cutoff.
