Title: Sensor is ineffective.
Review: The sensor is way off. It doesn't move or hoot until something is 1/2 inch from the sensor. If I knew it would not hoot or turn it's head like advertised, I would have not spent the extra money on the sensory kind. I would have just gotten a regular owl; as that has worked so far to keep the squirrels away. I chose not to return as I do not want to spend more money on S&H to return.
