We live at the bottom of a hill in New England, and the melting run-off and piles from the snow plows can create a really dangerous icy barrier to the main entrance to our house. These are the only things -- and I've tried basically all of them over 20+ years -- that have ever worked. Plus, less salt in your yard and on pet paws. These are warm, not hot, to the touch (I've seen cats lounging on ours), so very safe. They also don't seem to run up the power bill too badly, but I do try to unplug them when they're not needed. They melt snow at a good rate; in a blizzard they may get covered for a while, but they'll melt it off pretty soon. Plus, it's a wonderful luxury not to have to shovel the back walk. These are solidly made, which is why they're not cheap. I'd suggest comparing it to what you pay for salt or ice melt in the winter. If you're somewhere where that's chump change, these probably aren't worth it for you. But in Connecticut, it totally is. Not to mention that snow shoveling is a major cause of heart attacks and back problems, so what's that worth?
