Printhead is identical to the original in every respect and performs perfectly.


Wipes were handily included to clean printer parts before installation.
Instructions were really clear to follow and installation very simple.
Had to go through two printhead cleaning cycles before black ink would come through but once that had completed the printer has been working well.
So far really pleased with the quality and price and glad that it's saved me having to buy a new printer to replace my HP Officejet 6500A plus - would definitely recommend
