I'm thinking about getting a set of these although I'm still on the fence. Seems like a ratchet, extension, and socket would be better. On the other hand these might take up less space if I carry them. Anyone have them?

I saw them at Laughlin being sold by the inventer and his familiy.I thought they looked well made but like you said,a set of sockets etc- would be better. These are kind of limited and costly.
