So far, even more limited use, but given the doubts about the accuracy
of these things, I've specifically checked that over a room width of
about 3m, and it's accurate to less than 1mm over that distance, as
far as I could judge, probably to around 0.25mm.

And Earthquake proof according to the spec! :-)

Apart from anything else, what would be left to measure? Maybe I'll
skip on testing that :-)
