This item is not as advertised. It is not marine grade or water proof. Instruction say you have to bring in inside if a storm is approaching, really? It is suppose to repell out door animals! They do come out in the rain, right? The sound is also not ultra sonoic. It should like the boys from duck dynasty are blazing their shotguns in your back yard. False advertising and no returns, bad deal…
Sorry for your experience. Have you tried contacting CS to see what options are available?
