It is a 5-star rated air-condition in respect of electric savings. That was the most important criteria which I looked into before buying it. After using it heavily also, electricity bill rises by just 400 - 600 Rs. So in respect of cost- saving, this AC is really good. Now coming to cooling and comfort. While comparing to other AC this one is also really good in performance. It takes maximum 3-5 mins to cool down a room. So overall very much satisfactory.
