I like mine. Some of the powder coating has flaked off in non-contact points. The thing arrived with globs of grease on the plate and in the universal shell holder. I know why they did it, but still took a solid 20 minutes to get it functional for use.
You mentioned the micrometer issues, and while it’s an annoyance, there are workarounds like inserting it after the handle is already past the head and manually ejecting cases since the universal shell holder doesn’t get actuated.
Overall pretty happy with it. While I’ve never measured run out, I’m pretty sure it’s doing much better than my non-floating block RCBS.
