Query: Disappointed Consumer

The electronic owl that I purchased initially fulfilled the mission for which I purchased it--getting rid of the crows that frequented my yard. However, the owl lost its sound after one month's time. The sound device stopped working completely, and it is not nearly as effective in scaring away predators as it was when the sound was available. Since the owl has a sixty-day warranty, I am hoping the company will replace it.
