Ok, so what's the actual, legitimate use case for this thing? They show it lighting random fires, which doesn't seem like a good thing to do unless you also have a crew of firefighters handy... and those don't come flying on on drones. They show it torching a wasp's nest, but that seems to be the most overkill way of doing that.
