Im a return customer and highly recommend Australian Direct not only because of the quality of there products, but their customer service. Its easy to ask questions and trouble shoot problems thru Facebook messanger and there YouTube videos explains there products not only there best features but how it functions in your camping setup for example, I recommend there videos on 12v systems to anyone looking for dual battery solutions as there the only videos I've found to explain how it all works what's needed and what's not and is alot of help for anyone even if there using products from a different brand
