If you want to use a electric screwdriver unscrew a screw, it is O.K.,
but if you want to use a electric screwdriver to tighten a screw, it is a bad idea.
ching, no need to buy electric tools, I just use better quality screwdriver, that's enough, no need to waste money, use your money to buy "necessary options parts" for your car. I never use electric tools since I assemblied my first RC car back in 1980!
