if you buy the wcw one .dont forget to seal the gap between the top n bottom part ,to stop the water getting on the battery fittings n rusting them off .olso on the silver controller undo the screw holding it on n push some sealent into gap to stop water getting in or the cotroller will pack up . ps as a xtra precation i put a tupper ware container over battery just in case ..as u can tell from above i have had a few probs with mine .. mind you i use mine monday to friday everyweek so it has a bit of useage tacky
