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 Ryan Brunson

Just bought and had a chance to use it. I bought a large one because I drive a 2500 GMC Sierra. The windshield closed perfectly and I didn't have to scratch it at all. However, the mirror covers were too small and didn't work. I'm giving 3 stars because of the mirror caps and because I didn't feel comfortable carrying them over the truck. I've since attached a string to it to make it easier. Steve from downtown New York. Update December 3, 2018: Just had the first snow storm in CNY. 10 inches and wind and even freezing rain. I went to clean the truck and found that snow had gotten under this product. There was also frost on the windshield. Aside from that, the wipers didn't freeze and it took me less time to clean my windshield than if I didn't have them. I am demoting this to 2 stars and do not recommend this to anyone with a 2500 GMC Sierra. Steve from CNY.
