  1. This is a replacement 3 Star Review

    The first one worked fine for 3 years then the horn quit working, we continued to use it until eventually (2 more years) the entire unit stopped. Will not even light up. The unit is inside a kitchen cabinet completely out of the way and out of the elements.
    Hopefully this one last longer.
