hi all ceiling fans buyer,
my market study find out, the best ceiling fan is KDK, other may consider crestar and amasco. All other small brands you must think twice.
all china and taiwan make provide life time warranty for motor but problem always in capacitor, repair cost around 60 to 70 dollars. 1/3 of the fan cost. therefore , buyer's should check how long warranty for capacitor, i know one brand only 3 months, just imaging the quality of their capacitor.
so far, beside kdk, only crestar claim their motor can run more than 50,000 hours.
therefore, look for a better brand, ex KDK. You may go to individal brand show room to see how the company function.
