I had my light off once.
I turned it back on, if i remember correctly it was because the light did not blink.
And it ticked me off as i was going to the store.
I decided i rather it be on. As the blinking buys me ten minutes or so.
Now there are other times the blinking drives me nuts. Like when its on my bed side table.
One night my husband was convinced the cops were outside.
Nope just the provari. Didnt even think to turn it off duh.
Couldnt answer on battery life as i did it once.
