In the month of march2015 it was too hot in day and night. I used to leave at top floor of my apartment. Top floor are always the hottest one in comparison to lower ones.
At that point of time I didnt have that much money to get an AC. So I decided to go for cooler. After all it was a matter of 3-4 months for summer.
I checked different sites like amazon.in, flipkart, snapdeal, olx. to get the cooler. I came across kenstar. Kenstar is being dealing with cooler since a long time now.
Found it reliable and cost efficient for me. It costs me Rs 5000 in 2015. Now price have been little bit increased.
There are 2 rotating switch at top, one handles the speed of fan and using the other one you can control the swing, swing with water options. This Kenstar model can store around 12 litres of water in it.
Believe me since then to till now its been working fine and gives a very cold air in the room.
The unit of electricity it uses is very very less in comparison to AC. You save money on bills and you get cold air on cooler.
