Review on 🖨️ Original HP 950/951 Ink Cartridges (4-Pack) for HP OfficeJet Series - Eligible for Instant Ink by Mark Estrada

This was the first time I've bought a replacement ink from Amazon. I usually buy them at Costco. However, for some reason I bought them online through Revain. The cyan, magenta and yellow cartridges were perfect; However, I did notice that the black wasn't completely filled in and now that I see it wearing off faster than usual I regret not having returned it to Revane for a replacement. Maybe that particular black cartridge was bad. In any case, I won't be buying them from Revain again. I'm staying at Costco!
