This review is from: HeatTrak HR20-60 20-Inch by 5-Foot Residential Snow-Melting Walkway Mat, 120-Volt (Lawn & Patio)
I think these can work OK if there is very good drainage and this would be the case for the HeatTrak system for outside stairs. In my case there was no place for the melted water to go and it was a mess. Make sure you have good drainage.
