I know a girl who has two of them. I use to call her deaf girl kelly. LOL. What do you want to know??? They work, you can't see them unless you're looking for them and they are expensive.
Deaf girl is a riot BTW. She can read lips and that's just evil. In a club or something like that she can "read" what everyone is saying, useful skill. No one ever wanted to screw with her so my favorite thing to do was to start talking like a retard to her and someone would always look real uncomfortable. Kelly would then yell I'm deaf not retarded. LOL> Things would get more uncomfortable at that point. LOL. I was just surprised how women would avoid talking to her. She's hot so the guys would come after her but the girl's just didn't know what to do with her.
