I have purchase it on my trust on Samsung. But truly says Samsung may be good in mobiles and Televisions, but very poor in manufacturing Air Conditions. I have install it in my 10 x 12 bedroom. It fails to make my room temperature down. This air conditioner never cool my room since installation. Moreover it brings my electricity bill up to Rs.8000/- per month. Truly said I never advice to buy this Air Condition.
