Sienoc Replacement Ink Cartridges 1B+1PB+1C+1M+1Y Compatible with HP 564XL B8550 B8553 C5380 C5383 Pack of 5

They work well and hold a lot of ink. They are transparent and you can tell if they have any ink left. I use them in my HP 309a-m All-in-one. The only thing unusual is that the Photo Black shows a question mark and a different date for the warranty. The person that sells to Amazon does not answer questions and I don't know if the ink fades over time or dry out so I gave it 4 stars. Maybe the next time I run out of ink I will get the cheaper cartridges that are $3. cheaper and made by Generic.

They seem to work nearly as well as HP, with some perceived loss of vibrancy. The real issue is HP's mindless reminders that you are using a non HP product, and your printer's world may well come to an untimely end.

Works fine. The colored cartridges leaked a little ink when opened. Be careful with that, but they work fine.

Works fine. Copier only thinks it's half full though

a bit messy, I had ink all over by the time they were installed

I have used these for years . they work great and I have save a lot of money.

didn't work
