Review: As advertised - Item as advertised, Starrett is a great company for percision measuring. Use it all the time when I machine counter boars.
Review: Best mic for cutting blocks. - I'm not a machinist by any means. But I'm a diesel mechanic that more than occasionally has to machine cylinder counterbores (aka cut blocks). This is the best depth mic I have found for measuring liner counterbores. I was using the starret 2.5" depth mic at first and it was kind of ok. But I've found the half base depth mic is the way to go. It is much easier to handle and I've found the measurements are more repeatable due to the much broader base. I will definitely use this mic and only this mic for measuring liner counterbores from now on.

### ⭐⭐⭐⭐⭐ As advertised

### ⭐⭐⭐⭐⭐ Best mic for cutting blocks.
*by C***R on December 24, 2022*

### ⭐⭐⭐⭐ Operation is of Seconds quality.
*by C***N on February 12, 2022*

The lock seems to randomly rub the stem. This leads to inaccurate measurements at times. Seems like a second or less quality version. My other Sterrett micrometers are of a much better quality.
