Warranty from Nordman - advertising razvodilovo. Appealed - it started, they bought it in the wrong place, we are not us, in general they merged. Rubber at the time of the appeal has passed about 1000 km, brewed in a familiar tire shop, with a knowledgeable master, two seasons without problems. Pros: Rowing. Rows well. On the ice, too, it is quite normal. The spikes are a little worn off, but everything is in place. Cons below: Noisy. The new one drowns out everything in general, the engine, music, conversations in the cabin. Then the noise drops noticeably, but is still noticeable. Although rubber is not for clean asphalt, so this is not a particular disadvantage. Soft, you need to be careful in the pits.
