Recently purchased on May1st-2018. Bought it for 8500 in Hyderabad with Remote option as well.
Remote is very good so that we can power off/on, change the fan speed, Swing it, Cool on/off.
40 ltrs tank capacity is giving around 4-5 hours of cooling if the fan speed is set to Medium.
Fan speed can be set to 3 options - Low, Medium and High
There is also timer option available with this cooler.
You can set that to 1 hr, 2 hr and 4 hrs so that the cooler will be automatically shut after the specified time.
