I haven't been required to use one of these yet. I think the state of GA hasn't adopted the 2002 NEC yet and none of the contractors I know have been putting them in and no inspector has mentioned them to me.
I got one from a home owner that tried to do his own work and had replaced a GFCI with an AFCI. I plan to do some testing with it to see if they fail as often as everyone says.
