As for small micrometer it does not take up space and it has a good weight so it is useful. However, the stroke of the tightening screw is barely finished, and as soon as it is loosened a little too much, the screw will come off. I think that I will rebuild the tightening screw part and take the spring that is in it.
Although it is not being used much more, the crimp enters into the plastic knob of the tightening screw and 1/3 has come about to fall off. It is very disappointing though it bothers expensive Mitutoyo made. We will exchange for initial failure.
