I am using this Air Cooler at my home for few years. This Air Cooler is a very good cooler. It cools the room very fast. It runs with electricity and the air comes in all directions from this air cooler. Since I am residing in a very hot area I required it and the purpose got fulfilled.
The Capacity of the tank is very good. Only 2-3 full buckets of water are required for filling it up totally and it will run up to 8 hours. You can even put ice inside for getting cool air. My experience with this cooler is very good.
