A few limitations I would like to mention:
Since a shock protection is fitted rubber side of the housing, which is of course to be noted quite positive, is a lateral hang on a surface a little shaky because dess. Go, but only slightly tilted forward or backward, but the function diminishes in any way.
The opposite where the measuring point is to strike may not reflect all too strong. Glass surfaces or highly reflective surfaces make so many fairs a bit exhausting.
If something must be measured where there is no closure surface (eg long wooden floorboards, ...) need this only applied to a wall, or a suitable elevated degree are applied in order to measure correctly.
Otherwise, very easy on the battery recommended (first supply batteries in use for 1.5 years) >>> ABSOLUTELY!
