I got this product at Walmart on a whim thinking it would not work very well. Just the opposite, it has been a lifesaver. When there is ice on your vehicle windshield just spray the surface that needs clearing and then hit your wipers a couple of times to clear and you have a clean windshield within seconds. No wasting gas warming up your car for 15 minutes to do the job. No scraping is required. I was so surprised it was so easy. I just love it and will buy again when I run out.
