I honestly like Symphony Coolers because of thier low noice and good cold air. But they need to improve thier pastic quality in thier coolers. Also the water capacity is bit less so you need to fill the water tank often to keep the room cool. Other issue is with low quality water pumps which you also need to replace every season. But I think the same issue is with other brands too.
But Symphony guys provide excellent service and not too costly spare parts.
