I live in NH, and we get snow. I also use crutches and have severe arthritis in my R hip and knee. It's really hard for me to shovel and I don't feel safe when it's slippery. Therefore, I love them. I can walk to the car without slipping and if I forget to turn them on and want to clear snow from them, it's a smooth, ez surface to clean. They are easy to assemble, easy to operate, and are very effective. The one thing I do need to watch for is water that settles on the mat and turns to ice. However, so far, it's only been small areas. And if I had to, I'd throw some snow melt crystals on that spot. I was dubious but after reading some reviews I took the risk. I am so glad I did. Thank you!
