DeWalt DCD791 D2 28D56 Official machine! And cheaper than red analogs))) Brushless motor and electronics filled with compound = you can work outside even in the rain! There is a video on YouTube where it is lowered into the RIVER and it continues to work! I took it complete with a case, a charger and two acc 5A and now I just buy more carcasses (perf, umm, etc.) I chose Shurik for a long time, compared the characteristics and prices, but now I am satisfied, so I safely advise everyone
