Not bad dont forget to calibrate to zero

I let the local machine shop perform their magic where they do have the superduper micrometers that are critical for their operation

Dont crank them down very tight obviously youre not supose to do that anyway because i dont think they will hold zero

Thought for the money id get a piece of crap but was pleasantly surprised

I checked the included standards against the annuallycalibrated micrometers at work and they were dead accurate

I also checked the indicated measurements against the i gauging measuring tools that i have and found them to be equally accurate at least to the limit of my vision

The wooden box that they come in is rather insubstantial lightweight and does not fit the mics snugly but the box sits in my tool box anyway so it doesnt really matter to me
