I did not see anything that will really protect me from lightening. That lovely yellow white bright discharge of electricity and I have tangled four times over the years. And it is getting closer for last time three teeth and two fillings left me and acking everywhere for two months. I also get the privilage of gathering static electricity. My older screen for my computor and I did not get along. I could put my hand on it and it would go fuzzy. It nice to watch it dance across the sky and hit the ground but I can feel the static building. Just not good for me in some cases. There is a seperate ground just fo rmy computor just for me.
