I purchased and using from last five months.I am totally happy with the symphony diet 50T, because it saves electricity, affordable price& power consumption.the symphony diet 50T does not produce to much sounds like our old coolers.it cools very nice like air coming naturally.it feels like we are sleeping out of home.it produces air very cool and does not sounds to much, its too much quite than other air coolers.the symphony diet 50T is durable than air coolers at the same price.its plastic body is light weight and easy to carry and moveable.it is good product at affordable price.I am totally satisfied with the symphony diet 50T.
