Hmm yes... interesting that they can go out of calibration. I suppose if
the glass envelope is short and only supported at the ends, any tiny
change will put it way out.

I've got a big ol' 4' level back in storage in the UK - must get it
shipped over sometime. I'm surviving on a 2' plastic-fantastic one here
(plus the little one built into my set-square).

My Wickes 2'er is bang on though and so, by cross checking is my laser.

Laser? How posh and new-fangled of you.
