g&g ump problem

I have looked at various reviews of the g&g UMP (UMG) on Arnies, ASR, Airsoft Extremist and other websites and have heard good things about it. Just today, I read 3 reviews that the people had some problems with the gearbox and mainly the lack of a fuse in the wiring. Does anyone know if this is true and if it is, has it been fixed?
