Summary: A Great Toner Cartridge, A Very Poor Choice for Spacefighting
Comment: This cartridge works very well and lasts a LONG time if you are printing with it, but it DOESN'T work at all as a cold fusion power unit in an Yrolian space fighter. It can barely push the gravitronic stabilizers, much less feed the 45GW phase-pulse laser capacitor banks.
Get the TRAM-89 "Volken" cold fusion powerplant with the vent-blade cryocooling, instead. Save this cartridge for printing only.

Comment: This product is ideal for bulk printing jobs on the Brother 5250DN.

Summary: Brother Toner
Comment: I will only use genuine Brother toner after a negative experience with generic toner. I find the "high yield" a smart buy, producing copies at a much lower cost per sheet.
