These reflective waterproof accessories are a game changer for anyone who lives in a snowy or icy area. Through trial and error, I found that they not only protect my windshield from the elements, but they also reflect sunlight, making it easier to drive in bright conditions .The only downside is that they can be a bit difficult to install, but once they're on, they stay put and provide excellent coverage. Overall, a great investment for anyone who wants to make winter driving safer and easier..
