I previously purchased seven of these for the business; the first one cost me 4,200 more. All died in half a year, and these plow you change the brushes 4-5 times, 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. I changed the brushes once for a year of daily work with the guys from the Central Asians (it's hard to find the original ones). It will also last a lifetime if you utilize it as your own home.
