Hello friends, I would like to share my experience and honest opinion about the Birla mini air cooler which am using from last month. As I used the cooler day and night continuously, within 4 weeks the cooler was damaged. There was some internal damage in the cooler. After repairing the cooler the power was reduced and enough air was not coming as well as the air was not that cold too. The cooler was damage due to excess of use, this problem needs to be improved. I'll suggest you guys to go for some other cooler instead of this one.
