I am writing this post after 8 years of experiencing the product. Mind it, the product stands apart far ahead in terms of cooling and reliability. In 8 years no repair work has been done and this 8 month old machine works as well as new machines of brands like Hitachi and blue star.
Cooling is super fast and u get to see actual temp on display which comes down from 32 to 18 in 30 minutes.
Though AC makes more noise than modern light weight machines but it's not something to get annoyed of.
Mine is a non star rated version , I guess now they have also started building star rated products. Even if mine is consuming more wattage then new gen ac's , it compensates as I only need to run it for 2-3 hours in night and then one hour in morning.
Pros : durable, lasts really long, superb cooling
Cons : price, a bit noise , less features
It's a no frills serious business guy.
