Thanks for sending the black cartridge; unfortunately the printing is still not correct.

Written my review and posted it on trustpilot already. It is a positive review. Thanks for your prompt delivery in the seasonal mayhem.
By J Brandon on 8 April 2024
These are the recommended cartridges for my printer they easily install but I hope the extra cost relates to longer use.
