actually the audible alert gets a little wearisome after awhile *beeep* *beeep* *beeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeep* so the silent ones are nice, one with an on/off for the audible would be even nicer

if the audible alert on mine broke due to trauma I'd replace it for fear that some other part was damaged too
