At distances from 5 meters, it often cheats (adds) a few millimeters, but when accuracy is needed, this is not very pleasant. Compared with a professional bosh device. Sometimes it shows the same, sometimes it doesn't. At "small" distances shows clearly. Can be calibrated. How does the entry level go. And the user is satisfied (took as a gift). Yes, and sometimes it helps out a lot when you can’t crawl with a tape measure or a meter. In general I recommend.
