I bought it during my college days when I had a single room. I lived on the fourth floor in delhi. As you all know the heat is scorching in the month of May and June, this cooler served me well during these months.It comes with a 12 months warranty and costed me 5700 INR. The cooler was easy to carry and fills in about 10 mugs of water. Ofcourse it cannot survive the night without refilling once , in a hot weather. And the most problematic thing about it is that its perfomance decreases drastically when dust accumulates in its air filters.If you keep it away from dust strictly in indoor settings with windows closed, then the humidity level rises and hence cooling isn t effective. Hence, I would not recommend it to anyone, specially requiring a heavy usage.
