Symphony air coolers are awesome. I bought a Symphony aircooler in 2009, still now its working amazingly. It never created any problem for me still now. The durability and performance of the product is just too good.
The design and look of the product is also superb. Main thing is that, it consumes very less electricity. The customer support is also perfect. Cooling happens very fast. The sound is very minimal. Its totally a value for money. I would recommend it to everyone.
