Review on 🖨️ High Yield HP 55X CE255XD Toner Cartridges in Black for HP LaserJet Enterprise 525, P3015, and HP LaserJet Pro M521 by Robert Lemons

I work for a computer company that has used 20 to 30 HP LaserJet printers at any one time in the last 30 years (about 750 to 1000 cartridge changes) and I have never had a problem like this seen with HP toner cartridges. I have just returned my second twin pack and all 4 cartridges were defective. Trouble is, I've never seen it and can't even imagine it happening. The plastic strip you pull out doesn't come out. You can pull on it with pliers and it will just break eventually. If these cartridges aren't counterfeit, then HP has had unusually poor results at some point.
