I already bought 7 pieces of these for the company, I bought the first one for another 4200. For a year of daily work with the guys from the Central Asians, I changed the brushes once (it’s hard to find the original ones) All died in half a year, and these plow 4-5 times you change the brushes, then the anchor just wears out in 1.5-2 years of work and the cords interrupt this daily sawing with squeals, otherwise it’s just a bomb. And if you take it for a house for yourself, then it will last a lifetime.
