When the weather got hot, I was looking for an energy efficiency air conditioner. Being conscious of the high electricity bill I opted for the air cooler which only consumes 80 W of electricity as compared tp 800W in ordinary air conditioner. Moreover I hated those piping when we fixed up the air conditioner.
Thinking that this is energy efficient and no piping involved, I bought it. After the first use i regretted because the air that comes out is not cold at all despite of putting in all the ice and 6 bottles of frozen water inside the assigned compartments!
Cleaning it is a big probelm because there is no way to pour those water out from the compartment. The idea of the manufacturer is to use water vapour to cool the air like those mist fans do but it was a total failure!!
