Usha is the oldest company of fans. Their are many models are available of fans. I am using Usha ceiling fan 1200 mm since 7 years and till date their are no need to any type of repairing and any type of maintenance. The blades of fan is too long so it covers more area and provide air in my big room. I am also using other company of fans in my another room but they are unable to work as efficiently as usha do.
