Review on Kingjet Compatible HP 972X Black Ink Cartridge: High-Quality Replacement for PageWide Pro Printers with Newest Chip - 1 Black by Stephen Cernatescu

The ink runs out after 160-170 print pages. Wouldn't buy again. Instead, purchase a replacement that says "1600 pages." Update: Seller sent new ink and it works great. Perhaps the manufacturer's problem with the first batch. I wouldn't hesitate to buy them again. Customer service was outstanding! Upgrade to five stars. Perfect.
