I am using this cooler for the last 2 years and it is amazing. it cools very quickly as soon as cold water is poured in it. no tension of maintenance or servicing. it is working as good as it was working on the first day I brought it. just with a regular cleaning of the filter it works even better. it can store a good amount of water so after filling it once we dont have to worry for next 2 to 3 days. being white in colour it gets a little dirty some times but just by cleaning it with a wet cloth makes it look like completely new. at a price point around 6500 it is worth it. it does not make lot of sound.
