I purchase symphony jumbo air cooler for my room. My room is large and for this my cooler is perfect for my room. It cools my room hurryuply. Fan speed is very fantastic. Heavy motor that gives a better speed. Fan blows air very properly every where and even corner of the room.quality is awesome and durable. And also don’t take lots of area like other coolers. It has ice chamber features that cools a temperature quickly. Have mosquito net and dust filter. Color and design of this cooler is also very cool and stylish.it does not make sound.loved it
