Query: Was not the fan pictured or described

The fan was described as 4 1/2 x 4 inches and the picture matched the fan I was replacing. The fan I received was only 3 1/2 inches and did not fit or cool the unit enough. The seller would not allow a refund and the shipping would cost more to send it back. Live and learn I guess.
