14 mics and 500 miles
I am currently running sound for a touring music group with 14 of these mics.
There is only one button on this mic and it is in such a location that singers offen accidentally push it which mutes the mic; however, that feature can be (and on mine has been) locked.
The transmitter in the mic is not a stick antenna so if a singer gets daring and moves their hand down to base, transmission nearly stops
The five presets allow me to use the same mic for multiple groups at once with only minor changes at the board, and since each preset can be named it is clear at a glance (when the unit is on) as to who's mic it is. and most settings in the mic can be reviewed at the reciever so it is easy to tell if something is hinky.
All things considered: these mics are more than I expected for the money.
