The grip and handling are very good for the money (always as an economical solution). My main problem is that they constantly whistle on the roads in the summer (on an island) with the slightest turn. I wouldn't buy them again just for this reason.
Edit: I'm changing my rating from 2 stars to 4 because in winter, as soon as it snowed, they did a great job in Northern Greece on the snow, without needing to use chains. I wouldn't have made it through with summer tires.
