    CURTIS -- daniel island, SC   2/27/2014
    This is more of a "lack of anything bad to say" review, as we have no way to test the product's performance here -- and -- no massive thunderstorms yet since we installed it. It looks robust, is a simple design and strikes you as well made. It was properly packaged, instructions are clear, installation is simple, and it arrived just as promised.
