I suspected something was wrong when I saw the box had tape on one end. The cartridges were unpacked and all had a piece of plastic ripped off covering the ink outlet. I needed to print some flyers so I put them in and hoped for the best. The flyers were well received but were reduced by 25% (only 40 pages). That means I'll be lucky if I get 200 pages of it instead of the 300 advertised. They were clearly needed. Now I buy direct from HP. $38 is too much for used cartridges.
