Bluestar well company makes products for comman man. I have this AC in my bedroom . Performance is good but maintenance is hight it does not really offer 3 star electricity saving . I would just say my experience we brought it in last summer . After 1 month it start giving harsh noise I contact to services center and they send the guy and it was repaired agian same thing happen after 3 months then I fixed it locally . Overall air throws is great but can really improve . It still gices sometimes that hash nosie. Only one is good is its small size it get fit easy . Other then that I dont feel it gives something special. I reget why I make hole in my pocket for such stuff
