Jehu says he is some kind of electronics engineer. It is me, the atheist supporter of evolution who is a Civil Engineer. (and not really even that. I was pulling Jehu's leg as it happens, I just trained as a Civil Engineer and now work in software, so my qualifications to pontificate about this stuff are about as good as Simmons)
So if you have any safety concerns it should be about electrical devices designed by Jehu. ;)
Oh Jehu designs stuff. That explains it. ;-)
