One does not need often. But if to have, then you're glad such a thing :)

A very handy little tool that can not too often requires ID rule, but which one can sometimes facilitate life. So a combination wrench behind our (heavy) is currently two heating Install Expensive washing machine like it here. The wanted ansetzten to heave the machine aside! (Which for reasons of space anyway an act is). I've noticed that and said, "Wait, I've got something." Then I got where the telescopic magnet pressed in the hand and in no time the poor end wrench was freed from his predicament :) The guys were amazed about the little thing and would have liked to taken there directly. But we have not reached an agreement: D

Great little helpers.
