When this time I was changing my room in my college time I thought of having one air conditioner from green dust as I used to know that it is too affordable according to other shops.well I bought it but at the same price and after using it I found its too defective as its window AC .it has so much sound and not taking load of compressor .i have fitted one stablizer but still not working.Its really a green but I think its a Global dust .
