I like the size of this door mat, and the looped/rough surface seems like it would work well for wiping snow off your shoes in the winter.
It is very thin, which is good because opening / closing the door won't catch. If you want to put this outside though, be prepared to either weight it down, screw/tape it down.... or chase it across your yard when the wind blows.
While other reviews say it's anti slip, the one I have slides around quite a bit, both on tile and on carpet. I'm not sure if I'll resort to using two sided carpet tape or some other method to keep it secure, or if it's just going to not get used.
