Hitachi is the one I looked to purchased last summer and really gets disappointed.many of my colleagues were using some other brands and to be unique I have choose this and at almost using it for 2months it got some problem with the turbo and some times it will not power off need to be turned of the main switch and it was not really user friendly remote is not so easy to monitor and use.at great concentration I learn to use it and it was really waste of time and it wont get cool at very fast but takes some minutes to feel that.
So I have to start it an hour before to feel that and it was waste of my power bill.it consumes more water while using and it should be controlled.lack of quality remains this case of not functioning well.i have to give it the service center to make it working fine and because of warranty it helped to a lot not to keep my money from pocket.
