No grease used on the threaded pin dealy thing?
I for-see a LOT of kids cross threading this thing. Or installing it with the pin/threads going the wrong way and it self unscrewing...
Or maybe not, since the cost is so high, maybe the kids won't be buying it?
Odyssey makes some cool stuff but most kids are too dumb (or don't have dads to teach them) how to work on mechanical things.
Personally, I think this is a cool idea but I don't see myself buying one anytime soon.
