That's very funny, and a perfect description.
If these tools are crap (and how can they not be for $13?) The OP will discover that fact on the side of the road. As to whether it's "better than nothing," I'd say it's not. When you have no tools, you know where you stand. When you have crummy tools, you'll have an false sense of security.
But best of luck, I hope I'm mistaken.
