I've seen a few of these in my neck of the woods, and actually one of my bosses has one. They look like they could tackle just about anything that you threw at them. Maybe not so good on the trials as they are really long. They seem perfectly suited for the post-apocalyptic world.
"The major difference between a thing that might go wrong and a thing that cannot possibly go wrong is that when a thing that cannot possibly go wrong goes wrong, it usually turns out to be impossible to get at or repair."
-Douglas Adams, Mostly Harmless
