Product review (1 stars): Holes in fan blade do not match motor.
The fan blade that comes with this mounts onto 2 metal alignment pegs on the plate on the motor shaft, then 2 screws are installed through the other holes in the blade into threaded holes in the motor.  The problem is that once the fan is seated on the 2 pegs, only 1 of the screw holes aligns properly.  The 2nd hole is off by enough that you cannot install the 2nd screw and still keep the blade seated on both the alignment pegs.  Since this product is sold by a separate vendor and fulfilled by Amazon, Amazon will not replace the defective product, only issue a refund once it is returned.

I tried looking through the return policy info for Amazon, but have not been able to determine if I will be charged for the return shipping.  I have also tried to find a way to contact the seller, but had no success.
