Review on INKNI Remanufactured Ink Cartridge Replacement for HP 972A 972X - High-Quality 4-Pack for PageWide Pro MFP 577dw 477dw 577z 477dn 452dw 452dn 377dw P57750dw 552dw Printer (Black Cyan Magenta Yellow) by Terrance Palau

Contrary to the seller's claim that these ink cartridges are compatible with the HP 5700 series copier, they are NOT! After installation, the copier will notify you that the cartridge is not compatible. Revain no longer sells the ink I bought for our color copies at the office, but offers it as a replacement on the Revain store page. I received my order on March 24th, 2021 to have on hand if our ink needed replacing, but on April 28th I found that they were not compatible. The returns window is now closed. Big disappointment and waste of money!
