I am looking for a machine level and found these on eBay. Only one feedback was that when compared to another level they were not accurate. That to me doesn't prove anything as no claim to validate the reference level.

To my thinking if the base is truly flat and the tube is adjustable, which it is then these should be able to set up well. Am I missing something? Quality of the glass tube etc?

I would have thought simply turning it 180 degrees should highlight any error. They are badged "Industrial Australia" bit of an oxymoron these days and assume they are made closer to Beijing than Melbourne.

Thoughts?
