🖨️ HP 950 Ink Cartridges, Pack of 2, Black, Compatible with HP OfficeJet Pro 251dw, 276dw, 8100, 8600 Series, CN049AN Review

It looks like my entire batch of 951 and 950 XL printers that I ordered on December 24, 2017 are not compatible. I noticed that they are made in Malaysia and marked z10 for use in the US and Canada, but my 8630 printer will not accept them. The previous ones made in China worked. How do I get replacements for them that will work on my US purchased printer?

I bought 2 packs of HP 950 black ink. None of them work with any of my company's HP Officejet Pro 8620 printers. I have bought 950 cartridges from various sources in the past and have never had this problem so this is definitely an issue with this product. This is likely a scam and not a genuine HP product. DO NOT BUY THIS!

Another overpriced HP product but it works while generic 50-50 is crap (or worse). I have a drawer full of generics that are not recognized or recognized by the HP8600 printer. Very overpriced for the amount of ink you get. This is Gillette's tried and true marketing scheme, "Give away razors (printers) and beat them for the cost of the blades (ink)!" or as they used to say, "We got them from Nads"

Good product at a great price. I wanted to buy this product at one of the large local stores in Virginia where there are no taxes before the school holidays and save 4.5% sales tax. I ordered online to get it 10% cheaper after tax than in big stores. This product is exactly what my printer needs and works better than recycled cartridges. More sheets printed and no mess. I've been refilling cartridges for weeks and no longer need it.

I will judge them only by the quality and reliability of the product (not by my dissatisfaction with HP and their explicit attacks to other cartridge manufacturers and refills which are sold cheaper but HP printers are slowly but surely going empty due to error messages etc. I have a bunch of ink cartridges that no longer work in case someone needs them very good and as expected the ink on them shines empty fairly quickly even on draft printing, but they work well and don't give error messages…
