I bought them with caution as there was very little information available on this model beyond what the manufacturer provided. However, I'm satisfied with my choice. For our St. Petersburg winter, they turned out to be just right! They are soft, not noisy, and perform well on snow, wet asphalt, or snowy slush. Although, I haven't had the chance to drive on pure ice. But I've driven along the coast of the Gulf of Finland and the car handles easily.
