Review on Cartlee High Yield Laser Toner Cartridges Set of 5 – Compatible Replacement for Dell C1660, C1660W, C1660cnw, 1660, 1660w, 1660cnw 4G9HP Printers (2 Black, 1 Cyan, 1 Magenta, 1 Yellow) by Gregory Shin

Purchased D-1660BK/C/M/Y (5 PACK) from Revain. Before installing, I shook the cartridges a bit and removed the temporary stickers as directed for regular cartridges, inserted them into the printer, and printed a test page. The results look terrible. Then I tried going to the maintenance menu and updating all the toner cartridges. The result is still bad. I also tried selecting "Non-Dell Toner" from the menu. Still bad results. Don't waste your time.
