I am going to share my personal views about Symphony air cooler which I bought few days ago. First of all, coming to its advantages, air speed is good and also its size is big. But the.l important drawback of this.cooler is that because of.its design, the water inside the cooler is very difficult pour out and clean the bottom surface of cooler. Also due.to its large size, it needs more space in the room. Also, it is quite expensive and one complaint when it was being used by me 2 days ago was that it makes some unusual sounds while the fan is rotating.
