i think it just a selling point, it have no use at all,
but just attract people to buy it, when you know there have somethings, so what you going to do??
i do think there will have some people buy it,
because human is too curious on those things! especially teenager!!
but i think this is not a good thing to use,
cause when you along, and it start to ring, (that nean ghost are there)
and you know that, so you will start to fightened, i think,
when human fightened, our magnetic field will turn down
at the same time this sound attract ghost 2,
so easy ghost will come to you, then.....
of course, this will not so easy happened, but still have chance.
so i will recommend people not buy is better, or you have a special reason.
and i think this thing is so funny!!!
