Hitachi is a very good brand. I buy this ac because I have seen these ACs in most of the houses and its also used in my relatives house. I asked all of them wheather it is good or bad they all said its BEST. then I purchased this AC. its a very AC. it gets my room cool very fastly. I have used 3 star AC and it salo use less electricity than other companys ACs. although its very good but its price is also high . but I really liked it I think I do not wasted my money.
