"I fitted it I found it irritated me,so much so that I removed the buzzer..."
I know that feeling and that's a distinct advantage of the Audicator. You can set it for the number of silent flashes before it begins to sound and you can set a ramp function that allows you to choose how loud the warning gets and how fast it gets there. I never had trouble remembering at night, only in the daytime when the contrast is low.
