Has anyone seen a study that shows these move more air than any other vent of the same size![Roll Eyes :rolleyes: :rolleyes:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
I have checked it out, they don't make any claims like you would expect, if they really do better than flat vents.
