GOOD COMPRESSOR with rotary system I am really impressed with the cooling power of this wonderful machine.It’s cooling system is great plus machinery is user friendly. Most of the air conditioners doesn’t make their remotes of such range and we have to put temperature up and down by directly on Air conditioners that may hurt your sleep. Even your grandparents and your childrens can operate its easy coded remote. Moreover the best thing that makes your mind to buy it, is it’s great cooling power with less electricity bill and its metal body is easy to clean without spending any extra instrument’s. MUST BUY-REALLY GREAT PRODUCT.
