I am still waiting for the proof zappers can cut worms like celery, you know this can't be proven . I proved the opposite that electricity burns not cuts , it can even melt wire with a 9 volt battery . So if electricity burns how safe is long term exposure to zappers . You can't prove they work, nor can you prove they are safe to use . I prove my points and statements , you can't ,so ,if that makes me dense once again , I will take it as a compliment . I am dense with facts , not the lies ,distortions-deceptions etc etc you post daily .
