Today i used this tool to set up an acoustic guitar, measuring the string height at first and 12th fret. It is very easy to use and the scales are clearly visible. I appreciate the recommendations printed on the tool, I followed them and had a good result, the action is low now and there is no fret buzz.
However the finish of the tool is raw, there are sharp edges and corners all around, you have to be careful not to damage the guitar finsh. I used fine emery to finish the tool but that should preferrably have been done in the factory already before delivery.
In all a good and useful tool except for the finish.
