I bought this cooler in 2016 summer, and I have used it for one season. This cooler is nice in terms of air flow and cooling. People think it will work as an air conditioner but this is not an air conditioner this is a desert cooler and works on the principle of evaporation. The problem with this cooler is if you want to clean it from inside ( as we know after using water there is some dust inside the cooler ) you have to open it and for ooening it you have to give atleast 1/2 hour and then for cleaning. Opening this cooler is’nt easy even you can be in a problem if you don’t know how to open it. It works on inverter also. Its air speed is very good. I am almost satisfied with the product as its price is a lil bit high.
