📏 High-Performance Digital Caliper Micrometer by Anytime Tools Review

I use this thing every day. It's seen a pretty good hit and still reads true. (I know, I checked it using a set of micrometers with the standard) only one minus. One of the arms was torn from the abuse. It was an easy fix, just tightening the screw holding it to the pole.

Works well according to the measurements. However, the quality check failed as there is play in the side-to-side movement resulting in the spikes not touching due to misalignment. Luckily this doesn't affect me very often as I use it to measure the thickness of brake discs, which it does well.

More than accurate enough for the job it was designed for. It is not necessary to be more precise than a few hundredths of an inch on the rotor. If it really is that close to the minimum specs then put some new rotors on the car and move on. Holds up well. Mine is three years old now. Has a good weight, not like the $20 which is weak.
