nonsense questionPVI unless they're complex numbers.All devices are safe according to the regulatory agency that approved them using whatever standards they used.ALL DEVICES FAIL.Some catch fire.I once read in readers digest that a house can catch fire.  Does that allow meto make blanket statements about which houses are safe?Hint: NO.
