yeah that does look honking huge and out of shape
i just got mine back yesterday in smoke too!!! im still sanding the feed neck got a blister on my thumb now and took out the dremel so now it only goes on half way so far.
mine is also very quiet however it seems to kinda skip in movement(kinda goes like this rrrrrrrrrrrrrrrr*click*rrrrrrrrrrrrrrr and so on) every so often and doesnt seem to be moving at top speed
also they dont just give you an entirely new unit i figured that out because mine had some bluish white paint from neao2 in it and i can still see little bits of blue in the corners and stuff where the spinning thing sits on.
Yeah my mag's still better than your impulse.
