“Great products. Great customer service. One point off for the recent EDF units. They do run solid with excellent power. However, Freewing Fans in all sizes are consistently being delivered to the consumers with scuffed inner shroud walls (blades coming into contact with shroud while turning). This is likely from testing while hand holding the units at the factory. Easy fix is to mount in test stands before powering up. Please don't sell product that has been damaged. Thanks!”
