I have purchased two of the Scarecrows. The first one I bought and placed guarding my garden from a groundhog. It was doing a great job for a few weeks. I bought the second to cover the garden from two sides and would move them occasionally. I had to experiment with the water pressure to make sure both would go off. I the problem now is they have both stopped working. I have replaced the batteries, brought them in and cleaned them but still no luck.I'm not sure if it is coincidence but we had a group of bad storms last week with lot of lightning and both of these units have not worked since then. When it worked it did the job. But both units bought a few weeks apart are not working.
