I heard about this on a podcast the other day. I don't know a lot of the details but it seems like it's basically a really good/fast surge protector? For someone concerned about emp it's kind of a game changer if it actually works. They have a Christmas sale right now plus on the website prepping2-0.com there's a 50$ off code (not sure if both can be used at the same time). There's also an interview on that podcast that gives more details. Has anyone seen anything like this? EMP Protection & Defense Technology | EMP Shield
