If you want the cooler which gives you fantastic coolness in short time and also comes in affordable rate then I will suggest symphony ninja air cooler. I also have this cooler and it cools my room very quickly. The cooler has large water tank so it works smoothly for long time. The cooler also has remote control system that makes your work easy. I am using this cooler from last 8 months and believe me there is no problem with this cooler. I am glad that I have this cooler.
