Negative Positive
Title: It's not 8 inches wide
Review: Though it says 'Width 8 inches' and 'Easy To Mount Over Any 16'' x 8'' Foundation Vent', the cover is only 7 3/8 inches wide (outside measurement), so it will not cover a vent with an 8-inch opening; most foundation vents have an opening wider than 7 3/8, so the cover is completely useless. I had to return them all. If the opening on your vents is more like 7 inches, go ahead and order them, but be sure to measure.
