They have helped me a lot in extremely difficult weather conditions, especially since the car I drive has traction on the front two wheels. In fresh snow, it finds grip on steep inclines and during braking and turning. It also finds grip on ice. In the rain, it is equally satisfactory. However, in temperatures above 14 degrees Celsius, it wears out quite a bit. It remains just as good even after years of use (over 5 years). I am very satisfied.
