I have bought bajaj fans then I bought it. Boths service is very good at all. This bajaj air cooler is very costly than compairing to other brands. But its service & quality is also better than other brands. Over 2 years and not a single problem I found in this cooler. So this is a costly quality product I think. if you want a long service cooler than go for it. Im giving 4 star to it because of its price, otherwise 5 star for its quality & service.
