Hi friends, I am just share my persionl opinion for Symphony Air Cooler. I use this Symphony brand cooler last 3 year. I like this if that good work and cooling power nice. This Cooers no full sound less but sound make air flow, not that plastic body. Symphony brand use plastic good quality if that make this best. This brand coolers full value of money, just you not feel your waste money. Coy service and spport quality so nice quick respose when problem.
