The screwdriver reached Krasnodar in 11 days. Executed qualitatively. Here on the drill from the kit should not count-throw and forget. Disassembled added lubricants... And to collect, so that everything coincides-that's the quest. With 3 or 4 times only turned out. 1. collect on the first gear so that everything comes together. 2. Twist the case with self-nuts, starting from the back side (where the bearing is located)-the opposite cartridge. 3. there should be no slits when assembling the housing. The batteries were charged at 18,5 and 18,3 volts. The case is very compact. Product and seller recommend.
