Interesting. Basically this looks like a two-way clicker to help the player keep track of the running count in blackjack. From what I read there is no true count conversion or index number help. Still knowing the running count and betting accordingly is much better than not counting at all. It is also a clever disguise. However be aware that using any device to help calculate the probabilities on any game in a Nevada casinos is a felony and carries a punishment comparable to bank robbery.
