Bought at a special price as part of my Unzuges me the device. The instrument measures very precisely and enough for me as private users completely out. In particular, the fact that one (at distances of more than 2m more not having to bend over to the ruler and juxtaposition) is much faster and more convenient to results is pleasant. Also helpful for detecting mounting points for ceiling lights (set in the middle of the table and mark the laser point of the ceiling).
