Hi friends, I wanted to share my personal opinion about Symphony jumbo aircooler. I saw this air-cooled in one of my friend’s place and had got positive response from him. Later, I came to know that it was world’s one of the problematic Air-cooler. The looks of the product is good but the performance is really pathetic. When I bought the product I was promised that it will cool 4000sqft room area but actually it doesn’t even cover 50% of it because the wind blower is not that strong.Trust me, it makes a huge noise and vibration that I couldn’t sleep peacefully during night times. Guys, I strongly recommend not to buy this product as it’s an intolerable product and it’s a waste of money product.
