GLeo 2 It serves a purpose, but don't think that it is high quality. This is made in Japan, but the metal is very rough, flimsy, and cheap in quality and feel.There are better quality Outer Diameter Calipers out there.I could only wish for better metal selection and a higher attention to detail. I was very surprised to see that something like this was made in Japan. These kind of products make me worried about Japan's ability to build quality products.
