Review on FarBoat Vernier Portable Measurement Tool: Precise and Convenient Measuring Solution by Eloy Boelkens

This is not an accurate measuring tool. Supplied in a thin plastic sleeve with a "Made in China" tag. "Made in Germany" is engraved on the case back. There is no marking on the top for reading internal measurements in English units. I had to make my own sign for this. It can only be used for quick, approximate inside and outside measurements, but not for accurate measurements.
