Excellent products at a very very competitive price. Amazing quality and compatibility with printer. Very simple to install. I suggest that once the cartridge is empty, take is out of the printer and knock it lightly on a hard surface to loosen up powder that may be stuck, Then rock it the way aa a new cartridge. This may get youmore pages of printing. If we could get a clean way to add toner we could save on land fills of empty cartridges.

Always had the best luck with these and the last two have been duds.. terrible

The cyan toner stopped working properly after about 50 pages, left globs of toner on the drum that left streaks and lines on the paper and even transferred onto the other toner drums. The yellow toner leaked toner down into the printer and into the moving parts of the printer which now howls while it is printing. I will have to take printer apart to clean up the mess. Will be looking else where for toner for this printer.

Misalignment on cartridges. Blurry prints. Tried all HP tricks to correct/realign/etc. Junk. You want to pay cheap, you really get what you pay for...
