That's not the only negative. Noise is a big one. I have yet to find a cordless impact that isn't deafening while impacting. Even the smaller 12v impact wrenches are jackhammer loud (or seem so when in tight quarters). Pneumatics are much quieter in comparison and just another reason why I could never migrate completely.
you, my friend, have never heard a snappy mg31 w/o muff impacting on trans bolts while your head is shoved between the frame and trans then...you get a distinct ringing in your head for a few minutes after...haha
