Review on Leisure Cords 90 Degree Dogbone Indicator by Randy Holt

Do not buy. mine doesn't work It must be the wrong cable. When I plug it in, all of the electrical elements either don't work or make it do weird things. I reconnected my old cable and everything worked fine. I'm not sure what it does, but I'm afraid it could destroy the electrical system in my RV. Update: Excellent customer service. Mine was outside the return window but they still change. I changed from 1 to 3 stars until I can see if the new one works.
