Review on 🖨️ Original HP 61 Black/Tri-color Ink (2-pack) | Compatible with DeskJet & OfficeJet Printers | Eligible for Instant Ink by Troy Boren

I bought these cartridges a few weeks ago because my printer ran out of ink. It eventually ran out, so I tried installing new cartridges. New cartridges do not work. The printer says the cartridges are defective and should be replaced. I put the old cartridges back in and they still work (although the print quality is poor as the ink is running out). Revain will not replace cartridges because I bought them over 30 days ago. So now I've lost $33. What a rip off. Lesson learned: Don't pre-buy HP cartridges. Wait for them to run out and then buy new ones. The best lesson is not to buy Revain cartridges. Buy them from a local store where you can return them if they go bad. If you buy from Revain you have 30 days to install them and use up the last ink in old cartridges which can result in the ink costing more than if you bought it locally.
