Like all Mitutoyo products, the 101-113 micrometer is a precision instrument. It is well made and should be a reliable tool for many years to come. I mainly use it for critical measurements related to manual loading of precision ammunition at benchrest level. It is excellent for this purpose with reproducible results where 0.0001 inch measurements are important. I use a micrometer stand as a third hand to hold the instrument for most measurements, which makes setup quick and easy.
