No issues as such the LEDs stay on permanently now , no big deal, occasionally the hopper may not open , but thats due to human error , water generally comes in if you dont look after the neoprene patches that allow the hoppers to open on the underside , but these should last for years , I replaced them when I bought the boat to be on the safe side , so no problems. I suppose you could get water in where the batteries go but they do make covers for them , I havnt got them on mine though.
