I was so pleased with the first set that I decided to get a second one. The first set saw me through four seasons and several countries, including Georgia, Kazakhstan, Kola, and Karelia. Got pros: A favorable ratio of cost to quality; an excellent choice for individuals who are interested in traveling long distances, including over undulations and valleys)))) Below are some downsides: There are only a few of them, and in terms of noise (do not compare them to a highway; a perfect AT would be completely silent), there are nearly none of them.
