This is a good air cooler as long as it works :) If it fails then God save you as Bajaj has the worst after sales service arrangement. I had reported that my cooler is not working (think the water pump is broken) on 21st March 2012 and today is 26th and I am yet to hear from them. Numerous calls to them has not helped and all the customer service guy would say is "I will forward a reminder to the service center on URGENT basis" and that about it...God Bless you.
I wonder why we get so bad a service from such a good names company like Bajaj :(.
