Symphony aur cooler are known for their good quality air and strong built-in quality. The air from the cooler is fine but main problem is its sound and durability.
It's sound is too much that you will never run it at its full pace because you may not be able to sleep while night in that case. Also it is made up of low grade plastic which doesn't send to be durable at all. Once my motor got defective when I call executive they come in two days and repaired the motor within a week the service is not upto the mark as expected.
So overall the wind quality is fine but product can be more better until that the product is not a real worth of your money.
