I have a set for my WRX that I use(d) in the winter in MD.
They worked REALLY well on the ice/slush mix we'd normally get there. There were several nights when we were building the M725 (1:15 away form my house via backroads) that I'd need to drive home after a fog had frozen to the roads.
They work really good on ice, surprising... it doesn't feel normal when on ice, but you don't crash either

....
They are also hard enough to live through running during the summer if you get stuck with 1 set of tires.
They are a little 'greasy' on normal roads, but it made the WRX more fun to drive.
