The manager is very handy, though difficult. The steps are wide and not slippery. There is a magnet to which you can attach example screwdriver at the side of the black paper. The only drawback - I did not succeed, purely turn the screw in the black top, because the holes were drilled right and left obviously wrong. One can the essay but also simply stuck on it so he does not fall off.
ADDENDUM: screws in it. So no wrong drilled holes, but just not enough power. Thus a star upwards!
