What do you think of them?
load of old rubbish, or something to be wary of?
It seems to be a common view, even amongst those who are quite sceptical, that they shouldn't be messed with.
Any stories to share?
I'm asking because0I have one (never used) and I find my mind often wanders to the idea of 'having a go'. Too scared up till now though, and when discussing it with a friend, she had quite an extreme reaction, which took us both by surprise!
