I found a 2M one for $27, and a 1M one for $15. Pretty interesting, I definitely coulda used this when fishing for my IAT sensor that fell into the engine bay. Still have no clue where that lil funky bastard went!

Could make it easier to check for fluid leaks, and to spot bolts that are hidden from view (intake manifold ones come to mind) when doing maintenance.
I saw one of the regular USB ones came with a little screw-on mirror to see at right angles. That would be nice to have if you wanted to inspect wires in a rubber boot for any obvious damage like melted or damaged insulation and stuff with less tear-down.
Damnnit Aaron, now I want one too!
