I purchased a Blue star 1.5tn ac 3 months back and all I can say it is very efficient and powerful. It cools d room quickly ( it has turbo mode so that you dont have to wait for the compressor to load before cooling) . It is very easy to set up. A bit heavy ( around 50-55kg) . The remote looks good and both ac and remotes are made of good quality material. It has led display on the front ( blue star also gives u an option to turn off the led so that its light does not pinch your eyes at night) . The cust service is very good ( very fast and appropriate response) and the installation was very quick ( installed same day) and charge is reasonable ( 500 rupees) . Overall it is a very good product and no one cools better than Blue star. Go for it. It is a one time investment.
