These mats are awesome. I received them a couple days ago, just in time for the storm. I have one on my front walkway, leading to the driveway, and the other is in my backyard for my dogs to have a snow-free path out so they can use the potty. The mats are definitely keeping up with the snowfall- the one on my front walkway has even melted about 2-3″ around the edges of the mat on the cement. My elderly father comes over frequently, I am not worried about him taking a misstep and slipping now that I have these mats down on the driveway. The dogs seem happy to not have to break trail too.
