I would like to share my experience with reference to symphony air cooler which we bought in last summer.
We live in Hyderabad and we dont have a proper ventilation to our house. Besides that im pregnant and really faced suffocation all the day and night.
Then we bought this cooler for which I was very much satisfied. Lifting and moving is very easy but cleaning is a bit difficult task.
Overall its a good product and I highly recommend to you all
