I'm one of those Sliders. Watches...pppft! I can kill 'em in a few minutes. Electronics? I have orders to not touch my laptop in high states of stress...per my son the computer guy who has to fix what I do to them. He is a believer now. He's sat next to me when it happens. Light bulbs? I should own stock.
I've found it normally happens when I am not shielding and in higher stress states. My kids will actually tell me "Pull in the energy wave, mom!" They get tired of having to replace light bulbs...lol
