I bought it for home use, assembled 3 large 2-meter cabinets and a bunch of shelves on one battery and never charged it again. 2 speeds: for drilling and for screwing in screws and self-tapping screws. All buttons are pressed and switched easily and without jamming. Comfortable, light and not expensive Shurik. Pros: 2 Lithium-ion batteries without memory effect, lightweight, comfortable, long-lasting charge, case, backlight and hand strap, high-quality assembly. With its cons: 1 bit included - immediately throw it away and buy a normal set.
