Title: reasonably priced laser
Review: For the price this laser lavel can not be beat. Installed molding in a large room with a vaulted ceiling. After making my line on three walls I put the level on the third wall and prayed. It was dead on (sigh of relief). The self leveling mechanizm makes this tool a no brainer.
