Remember: as veteran flingers have said over, and over, and over again in the 'infamous $9.99 MB" thread: this is a mystery so don't complain no matter what you get! Fling isn't promising you anything but 4 Monster cables. They may be outdated cables that are of no use to anyone any longer Composite video or even s-video. You may get 4 of the same cable too. I don't think many people would get upset over that. That's what you expect from a mystery box.
With a Thing Fling MB however, you get even less! These cable may be too short to use 3 inches long maybe - they didn't promise that they would be long enough. Of course with Thing Fling they may not work!

You can't return them if rats have eaten through the packaging since they clearly state "Thing Fling will not accept any returns."

They may not have connectors either, who knows?? The biggest thing to remember is: you may be able to get the same stuff on e-bay for MUCH, MUCH less!
Have fun flinging!
