Well, the one I have works, and it doesn't take too long (in my opinion) to program it. In fact both players can program their side at the same time simultaneously since the game keeps track of both player 1 and 2's sliders. However I can see it being an issue, the sliders sometimes stick. Also, the game doesn't seem to care in the slightest bit whether you're actually programming 17 spaces in the form of 5 ships, you can in theory leave ship spaces randomly all over the board. The game also doesn't keep track of turns either, it is up to the players to decide how many shots each gets etc.
