I've been using compatibles on my printer for the last 4/5 years as HP cartridges are eye wateringly expensive, £100+ for a new set!. HP on one of their updates have stopped my printer from accepting them!. So looked on Ebay and found these HPs. Although long dated, about 2018, I bought them and they work OK and for £40 for a full set, they are a GOOD BUY. Will certainly use Ebay again to look for my next set. I would recommend anyone to try the out of date cartridges, rather than pay the ridicules prices charged by the manufactures for their upto date cartridges.
