Review on Holite Micrometer Electronic Conversion Resolution: Accurate Measurements with Enhanced Precision by Daniel Russell

I've been looking for a decent outside micrometer for a long time. was very close to getting the $400+ but opted for this one instead just because I wasn't sure I was going to use the $400 microns ha. I use it to design 3D models for printing and I have to say that because of the accuracy that 40 micron tolerance is spot on! I'll probably order another one for my "on-the-go shopping bag".
