Title: Unreliable at night
Review: Nice idea, but right from the first day, even with fresh batteries, I'd go out at night to test it with my hand, and it would not trigger, regardless of the sensitivity. During the day it worked just fine. I'm near Los Angeles, so the weather is not an issue. I bought it months ago, and only opened it this week, so I can't return it. Make sure you test yours right away.
