Symphony air cooler is best air cooler. It has a large cooling pad with dura-pump technology so it spreads cool and fresh air with high speed. It has long time working capacity so I can runs the cooler as long as I want. It creates only one type of noise that is, its cool airflow. It has feature like empty water tank alarm which is more helpful to me because so many time I forgot to fill water in cooler tank. My electricity bill is not affected by the cooler because it has feature like less power consumption which is good for me and everyone who not purchase the cooler for savings. This is the best thing I purchase in very good price. Truly it is value for money cooler.
