I've seen a few of those guys' videos before and they're absolutely terrifyingly dangerous, including playing around with unshielded magnetrons and so on. As far as I can figure out, they're in the area of Ukraine where the Crimea conflict happened a few years ago. One of their videos is about going to a bloggers' conference in Moscow and you would really feel for them. They're living a rather frugal existence and had to basically hitch hike to Moscow. It's a rather stark look into life in what is basically a very isolated and impoverished place where health and safety rules are the least of their concerns I suspect.
