In places where basements might flood, those leakfrog things are apparently pretty cool. A co-worker bought 3 for his family, because their basements are prone to periodic flooding. If it gets wet, an alarm sounds.
But about those radar detectors. Those that have them are only fooling themselves with effectiveness, at least in most locales. In smaller towns, they might have older tech, and even some larger towns you have officers who drive around with their moving radar on and light your toy up like a Christmas tree. But for instant-on, laser and VASCAR systems, they are completely useless. By the time you react to the laser notification, you should probably just start pulling over.
