A few weeks ago when the cold and snow seemed never ending, I decided to try out the Pro Tek Weather Shield. It's basically a windshield cover that is suppose to protect from frost, snow and dirt. I wanted to try it because anything that will make my early mornings a little easier is worth trying. I put the cover on one night when I returned home from work and hoped for the best. The next morning as I went outside in hopes of not having to scrape any ice from my windshield, I noticed the Pro Tek Weather Shield had completely blown off and therefore, I had to scrape the frost from my car. It has magnets in all four corners that are suppose to secure it to the car, but in my case this didn't really help. I tried it again a few days later during a snowfall. It stayed on throughout the night because the snow was heavy, but in the morning when I pulled it off, I had to use the snow brush anyways because the snow just went all over the place. I bought the Pro Tek Weather Shield at Showcase for $9.95. Although not expensive, it definitely wasn't worth it. Drop it. It looks like the old fashioned way of removing frost and snow is just going to have to do.
