As an industrial and scientific buyer, I purchased this measuring tool for my workplace needs.However, as a result of my tests i determined that the measurements were consistently inaccurate and unreliable. The parallel balancing feature proved difficult to use and frequently led to errors. And while the tool is advertised as multi-purpose, it fell short of our expectations for dimensional measurement. The only pro is the affordable price point, but it’s simply not worth the frustration and time wasted from incorrect measurements..
