Wood drills great. I drilled Chinese metal 4 mm with a Chinese drill 10 mm from the kit - like clockwork! Concrete does not drill even in impact mode, as expected. Still, the shock function here is more like marketing, of course, it will not work to beat them. But foam concrete blocks drill normally. As a drill and a screwdriver, it works perfectly, there is a supply of power (at the second speed, it twists the arm a little). The declared torque is 45 N * m. Voltage 20V. Self-tapping screws 10 cm long drove into a tree without any problems even with a minimum tightening force. On the drill itself there is a charge indicator light (green - yellow - red) - this is a plus. The battery capacity seems to be small, the operating time depends on the nature of the work. A full charge (green charge indicator) was enough for me to screw 32 pieces of self-tapping screws 10 cm long and about 20 more pieces of medium screws into a tree, after which the discharge indicator turned red, but the device continued to work without any hint of fatigue and lack of charge. The battery charges quickly, from zero to maximum in 40-50 minutes. There is a flashlight on the body of the drill that lights up when the trigger is pressed. The delivery set is as follows: a plastic suitcase, it contains a drill itself, a charger, a 2022 mAh battery, a set of drills of different diameters and bits in a plastic case, instructions in Chinese.
