Once the Magnetizer pulled over my screwdriver and already stuck all kinds of screws, everything could be safely dismantled and could easily place the screw on the screwdriver and control so precisely into the thread for mounting.
However, the "degauss" function works only mediocre, my screwdriver have anyway even after demagnetization at even magnetic properties, but much weaker. A screw yet still adheres to it.
All in all, however, I am very happy and satisfied!
