I actively use this saw. A year of use showed that the choice was right. It always starts without problems, and it does not matter when it is cold or hot. No smoke, almost no vibration. The length of the tire is 40 cm and there is enough for the construction site and to prepare firewood, and so on the site either cut the branches, then trim something. The chain is made of high-quality and not soft metal, sharpened normally. The chain size is 57 links, standard modification, so you can buy a universal one. Tools for maintenance included, no need to purchase anything.
