Got this one while visiting Broward area caches with a friend. I took it across the street and used it while playing slots...NO LUCK. Put it in my pocket while playing video poker...NO LUCK. Put it on the table when I played Texas Hold-um...Left the table with over $1500! Yessss! As much as I hate to do it, I am heading South and will drop it in a cache on my way to the keys!
