Failed after a few weeks, but I'm outside of warranty period
I would not recommend this unit at all. After only a few weeks of use, every other printed page jams the machine. Waste of paper and waste of toner. Because I bought this unit as a reserve and didn't use it for a while, it is now outside of the warranty window. My recommendation: Test your toner and drum units when you receive them. Then when you're satisfied they work, store them for future use.
PROS: Cheap, but you get what you pay for.
CONS: Stopped working, every other page jams printer.
