Query: Toner cartridge as good as new

This replacement toner cartridge is advertised as "compatible" with the original. Indeed, it works very well right out of the box, in the ML-2010 printer. The print seems somewhat darker than with the original, so I use the light setting in the printer options, to save on toner. Because of this (minor) difference I only gave the cartridge 4 stars rather than 5. A similar cartridge has been working for me in another printer for 6 months without fail.
