I HAVE BEEN USING ONIDA’S AC FOR THE LAST FIVE YEARS. IAM COMPLETELY SATISFIED BY THE PERFORMANCE OF THIS PRODUCT. IT HAS BEEN PERFORMING CONSISTENTLY OVER THESE YEARS. I HAVE NEVER FACED ANY ISSUES WITH IT. IT DOES NOT MAKE ANY SOUND . ONLY ONCE I HAD TO GET IT REPAIRED AND THAT HAD COST ME 1700/- BUT THAT WAS DUE TO VOLTAGE FLUCTUATION. THIS AGAIN GOES TO SHOW THAT IN CASE OF ANY PROBLEM IT IS EASILY REPAIRABLE .ANYONE PLANNING TO BUY ONE CAN SURELY GO IN FOR ANY OF ONIDA’S MODEL.
