This toner delivers sharp, professional prints without the hefty price tag. A budget-friendly essential for quality-conscious users

Does what it says, easy to fit, works fine, and 2 pack as well.

Never make direct comparisons in print quality from pre-used laser toner cartridges! There are too many variables. I fell foul of this soon after purchasing this four pack (in sets of two bags). My previous cartridge had produced a rich and vibrant black and this new one seemed a bit weak, a bit under-inked. I particularly had to darken my photo at the tailend of the first page as with the previous settings it looked ghostly.But they say that you get used to things and after my near-disastrous flirtation with Green 2 Print I am running these cartridges nicely. They fit the machine well, appear to be fairly long-lived and don't seem to have any distortion of the impression. Apologies to the seller for posting negative seller's feedback - hope this makes up for it!

Replacement HP cartridge. On installation the machine warned you were inserting a none genuine toner. Warning disappeared and then starts to produce prints that are perfect and have no discernible difference in quality compared to using an original toner. How can HP justify over £140 for their high capacity cartridge when these cost a tenth of the price?!? Very happy about the print savings we’ll achieve!
