Review on FrostGuard Winter Windshield Mirror Covers Exterior Accessories by Brandon Woodson

Quality material, beautiful design and easy to calculate and install. I ordered a standard size which is about 2 inches too narrow to fit on my windshield and leaves a 1 inch gap on each side of the vent. along the bottom edge. It was not possible to use the two PVC stiffening tubes on the edges of the vertical ducts because then they would not lie flat on the windscreen. Only one PVC pipe was used in each vertical duct, pushed through the top of the duct for stability. The XL antifreeze size will be 8" taller so will NOT fit my car so this is the only option. It would be nice if they had a 2 inch wide vertical extension that could be zipped closed for a more precise fit.
