DAIKIN IS SUPER BRAND, WORKING EFFICIENCY IS EXCELLENT, COOLING IS GOOD. INSTALLATION SERVICES ARE VERY FASTER AS SOMEONE BUY THE PRODUCT OF DAIKINS AND THEY PROVIDE SOME VOUCHER TO WIN PRIZES THAT I FOUND VERY NICE IDEA TO GIVE POPULARITY TO THE PRODUCT. INDEED ITS GREAT RETURN OF MONEY AS WE USING THIS PRODUCT FOR SIX MONTHS. I PURCHASED THIS AT PRICE AROUND FIFTY THOUSAND INDIAN RUPEES. INSTALLATION CHARGES WERE INCLUDED IN THE WHOLE COST OF PRODUCT. I THINK ANY PRODUCT CAN WORK FOR LONGER AS WE TAKE CARE PROPERLY WITH GIVEN PRESCRIPTIONS BY THE COMPANY.
