I recently purchased hi cool symphony cooler 31 litre for which one fin for swing was deformed manufacturing defect, often produces smell of rotten egg though I changed water everyday produces too much noise as compared big desert coolers one can’t sleep when cooler is on though dealer told me that small cookers have low noise , no ice box available for the price below this product I was getting 55 litre with low noise this ds I presume is loss of money
