Crompton Graves product is good but it has some problem. Water cooling line not fitted into the pump also found water leakage from back side of the air cooler while running the cooler. Water not supply to cooling pad properly. And also one more major problem while switch on the cooler, it generates more noise compare to other companies. It should be need to reduce the noise and improve the horizontal wings. Which restricts the area of direct throw of air in horizontal direction, Cooling is some what nice. But cooling is some what nice . Buy cooler is very good. Remaining parts of cooler is ok except some manufacturing defect.
