I have yet to wear one, Its supposed to keep tabs on who is playing or not right? I think the only reason I haven't worn one is because Zach knows who I am personally. I only spoke to one person who said it was annoying. He looked back at me and asked if we needed to wear them the whole time and then ripped it off. Why not try a stamp or something less irritating to a players hands? maybe some sort of sticker?
