I had great luck with the first batch I purchased of these but not so much since. I have been using these for a couple years now (all colors). Some work great for a decent amount of time and others just fail for no reason. Just replaced the print head on my printer thinking that had gone out but instead it was just these cartridges. The black is still mostly full and you can hear the ink in it when you shake it but doesn't come out. The yellow says near full but not working at all.
The good thing is the price, buy several to have on hand and probably still be money ahead.
Just bought a B/W laser printer, tired of these ink problems! Still going to fight with this thing for color printing
Unfortunately the printer wouldn't print black ink with this cartridge installed (HP makes it too difficult). Thankfully Monoprice has good customer service and setup an RMA for a return/refund. For the price, it was worth a try!
PROS: Excellent Monoprice customer service, great price
Thank you for your review and sorry to hear of the issues you have experienced with the ink. Upon reviewing your order I can see that the RMA process has already been started. I would again like to apologize for the ink not working. If there is anything else we can do for you please let us know.

I have had nothing but trouble with the printer cartridge in my HP Officejet 6500. At first, it would warn me about not being a legitimate HP cartridge, but would still print. Now it says the cartridge is missing or damaged and refuses to print at all.
