Four months ago I bought this symphony diet 50T air cooler and truly speaking I am really very disappointed with this symphony air cooler I thought it will keep my house cool during Summer but what I discovered was that it dose not cools my house at all I kept it on for whole day but then to it didn’t cooled my house and not only that it also consumes a lot of electrical energy and I revived a very high electricity bill this symphony diet50T air cooler has disappointed me a lot so if you are thinking of buying this air cooler then its my strong suggestion not to buy it because it is not at all good
