The fan arrived in good time and appeared intact and looked good.  When the fan was installed, it wobbled ferociously.  Instructions were followed to try to balance the fan out with washers but it was found that the motor hub assembly was way off centre within the housing.  With a lot of effort and time, the fan was made less wobbly.  It still has a slight wobble, but that was the best that could be done due to faulty assembly of the motor within the housing.  It looks good however but only with a lot of effort was the fan made useable although not perfect as it continues to wobble a bit when turned on.
