Could the answer be "Why Not?"

I just realized that many members have these...and I am not sure why. What does owning and connecting a battle counter do for a pachinko game to make it more fun? Is it like owning an authenitc pachinko stool? It does "nothing" but looks cool?

I am not sure what a battle counters purpose is in the casino to be honest but I know it is tied into the game somehow. Just curious why people want them in their houses too...or just for that "authentic feel".
