I got a screwfix catalogue last week that offered some levels by Forge
Steel. They have a self levelling one for £37 49 and a Rotary one for
the same price. Yet the bumph says that they are both self levelling.

Both are class II whatever that means, the first has a 10 m range
whilst the rotary has a 30 m range. So what are the likely differences
anyone know?
