Very good device to tidy price. With double Pythagoras function, switchable lighting and well audible beep (also can be switched off). Especially good: The 20 measurements or calculations great memory. Unlike many other laser measuring devices can be regarded at Milwaukee the stored measurement results not only, but also use them directly for an invoice. Say, for example, I once measured a length that is in memory, I can with this and another measurement example berehcnen an area or with two other measurements a content. Many other devices a measured length is saved, but you can only view the value, not work with him. This of course makes little sense. In Milwaukee, however, this is a good solution. Alone for thinking along from me it has four points, the last still for maneuverability, stability and handling.
