At first I was guided by Hitachi DS10DAL, but thanks to the Market I found this model only a couple of thousand more expensive (I took it for 8,000, although the price in retail stores is ~ 10,000 thousand). I made a choice in favor of power and reliability (I really liked the professional hammer drill of the same brand, which a friend brought from work for repair, he also shared his experience with DeWALT screwdrivers). It's funny that the production is written on the batteries - Korea, everything else - China. The device turned out to be manufactured in 2022, which is very good. The second battery (spare) was even fully charged! Whether he held a charge from the moment of production, or was serviced, both options speak in favor of the manufacturer's service. The battery that was on Shurik got a full charge in 15 minutes. It sits perfectly in the hand, the handle is rubberized, it is balanced by weight. If you put on acc. , too, "will not nod." Another nice addition to this Shurik is that it has protection against engine overload, that is, the engine will simply stop. And protection against discharging the battery to "zero". The charger measures the battery temperature. before charging if it is very cold or vice versa overheated, it will wait for normal temperature before charging. Designed to extend battery life. In general, it is universal, as it has already been written here, it can charge an acc of different voltages. In general, if possible, it is better to pay a little extra and you will be sure that the house will have a cool device, not for a year, two or three. By the way, in the passport it is written that the service life is 5 years. Warranty 1 year.
