Query: The biggest POS- don't waste a penny on this thing

Put new batteries in and it worked for 1 minute and stopped. We could not get it to work again. Unfortunately we waited a month to open the package and missed the return window. In the garbage it goes. A HUGE WASTE OF MONEY. It is almost criminal Camco can get away with selling such cheap stuff that doesn't work. They should be ashamed.
