At first I was delighted with the cordless screwdriver. Long battery life, very handy and convenient. To screw small screws into pre-drilled enclosure boards, certainly adequate. As for me then but disappointing: When trying to unscrew a probably pretty stuck steel bolt from the plate, it made no great force "cracking" and the engine was running in the "idle", the insert bit no longer turned with. Since the gears not seem to be of a reasonable quality. Too bad. Using a screwdriver, the screw was then but unscrew.
