Used may coolers before but this cooler from symphoney that is Symphony ICE cube I ordered via paytm and got it within 3 days and I am using it from past 6months and this is really helpful to beat the heat of uttar pradesh where temperature goes around 42. This cooler has honeycomb based cooling which is better than normal cooling as their is no grass( khas) .
We can arrange the blades too as per our requirement and can also enable the swing mode which cools every corner of the room. My room is of 250sq feet and it cools it in 4 hours and brings room temperature at 15 degree celcious.
The only disadvantage of this cooler is that the water tank capacity is only 15ltrs which is not that much good because we need to fill uo it again and again.
