Very good points Charles and Theo.
I'm convinced, thanks.

Mate hired one to do some work on his mates two story bungalow design
house gable end and it said it was unnerving wobbly, reverting to a
frame / scaffold thing for subsequent works.

Not suggesting it got close to falling over but I think he said you
have to pay very close attention to the stability and levelness of the

the weight of the thing and the fact that it's 'mobile').
