This air cooler is much reliable then others. We can easily shift it form one place to another with the help of its stand.
Because of its big water storage capacity, it can easily store upto 50 liters of water and we don not use to refill it again and again at a diff of short time period.
It can not produce much sound which disturb anyone or other type of any sound. We can use it from last 4 years and we does not found any type of problem in it.
