The first, exactly the same, worked for 1½ years in rather difficult conditions, in which a shura of this class, in principle, should not work. In general, with a bang, he coped not only with his tasks. In the end, he died a heroic death. And then the new year, and the DR, and some other bonus there. In short, I gave 5917 for this, took it in early January. Now I have 4 batteries, 2 suitcases, and the old old charger is sold on ebay.
