I am rajat. I have been using this product for more than 2 years. The quality of the product is very much good . The cooling of the ac is very much good and there is no sound. Once you have done the ac on for 5-6 if you turn it off the cooling remains for 1 hour. The major quality of the product or company is that the service is very much good. Once you call the service centre you vomplaint is resolved within 24 hrs. So overall I like the product as well as company very much
