Chennai is a place were air conditioner and cooler are the basic neccesity of peaple. I am useing bajaj dc 2009 air cooler frm past 3 years . It is not what v were looking for. the air in it is red hot during summers. water doesnot gets properly mixed up with the air . rotation process of the cooler is also not good .it worked better for the 1st 6 months then it started making noise from it . Hope bajaj cooler could work more on it . It should be strong and even in allocating air. Noise s the main demerit of the product .hope the company works on it soon
