I have a couple of friends using those too, they love them. My stepdad had them on his EM1 for a few years, he also liked them a lot. I personally think there are better tires out there, depending what you're using them for. If you have snow where you live, but you run snows in the winter, get something more aggressive, like Pirelli P-Zero Nero. My roommate runs those on his RSX type S as 3 season tires, and blizzaks in the winter, and they are pretty amazing for 3 season tires.
