Being in a transferable job, I preferred to buy an air cooler that is portable and easy to operate. It is then I came across Symphony Hi Cool. It is sleek and easily transportable. I even move it to my kitchen when days are warm. Another major advantage is that it is not only convenient to use but also simple to clean. Since I use hard water for the cooler, the spray holes get blocked often, but there is absolutely nothing to worry, I open it myself and clean it, it is a childs play.
Take my word you will never need a service personnel. Coming to cooling, of course one cannot expect the effect of an a/c but for the money spent, it is definitely worth it. What more would one need, the power consumption is equal to a ceiling fan.
So, go save electricity with this marvelous air cooler.
