This is the type of item that you don't know that you need, until you see it. Then you can't live without having one in every car. For the price, I'd rather be safe then sorry. It's worth it, just in case.
Good to have
I didn't even know things like this existed. I think everyone has a secret fear of their car flying off the road into the water or something like that. Actually, this is good for anyone in that type of trouble, a lend-a-hand tool.
