Review on FrostGuard+ Winter Windshield Cover with Enhanced Security Panels, Wiper Blade Cover + Mirror Covers - All-Weather Resistant; Protects from Snow, Ice, and Frost (Black, Standard) by Brian Rogel

Good quality material, nice design and easy to install. Each side has a vent on the bottom edge. Couldn't use both PVC stiffening tubes on the edges of the vertical duct They didn't lie then right on the windshield.Only one PVC pipe was used in each vertical channel that pressed against the top of the channel for stability.The size of the XL antifreeze will be 8" larger so will NOT fit my car so this is the one only option. Would be nice if they had a 2" wide vertical extension that could be zipped up for a more precise fit.
