Yeah, the only thing I don't like about it is the price. $99USD would be more inline to what I was thinking. I guess that extra $50USD is to cover the cost of the app development. The different colours are cool. I see myself playing around with this for a while a first until I settled on a design I liked and then just leaving it like that. So the app would be wasted on me. The flasher integration seems cool, but I don't really understand how it works. They didn't go into much depth on that.
Of course the thing that would really stop me from buying this is that one time I forget to remove them and busting the shit out of them as I lift the playfield.
