Milex 15L air cooler.... Needs to go back to the drawing room!!!

Please note when buying this: You cannot take the water bak out to fill unless you remove the pump and wires first!! Water goes dirty VERY quickly My ones sleep button does not work as it should and its +-8 days old. It fluctuates between quiet & blaring loud. The water level in front is not easily visible without crawling around on the floor. I phoned them this morning but they don't know their products!!! Cannot recommend
