It's good quality and is very accurate. I use it all the time for cnc milling setups.

As close as I can tell, it's within 0.0001 on every dimension. Close enough for me.

One roll was parallel to 0.00015", other roll was nearly .0007" off. Short side faces were significantly off square (0.002").

So I don't know if the unit is actually accurate enough. What I can say is that it arrived in an envelope and the box that the sine bar was in was completely crushed. I have received precision equipment in the past and they usually do a very good job of keeping the equipment fully protected. Unit also felt a little rough in terms of finish.
