They do try to electrocute their users if they're the wrong ones. I
once had a 24V version for car use and a 400V (?) for domestic. Guess
which one I used to test a mains wire?
Well, some would say that was the user's fault as the 24v one wasn't a
neon but a bulb indicator (neons generally only work above 80-90V unless
there's significant radiation or strong radio signals around) and the
user should have known what tools he was about to use.
