It's a good example of clearly addressing a specific threat model: it doesn't try to be impossible to cut (although the marketing material says otherwise...). Instead it's just so thick that a 5" angle grinder can't reach all the way through it in a single cut, and the coating material is specifically designed to be slow to cut through so that it takes a long time and requires multiple batteries. Of course, it still has the obvious problem that the thing you're locking it onto is probably a lot easier to cut.
