No flaws were noticed in the screwdriver itself, but the charger was sent defective, or the batteries were defective. We bought it in December, the screwdriver sat down only at the end of January, we decided to put it on charge, but it doesn’t work, the red light blinks and that’s it, after a couple of days we decided to check it, plugged it into another outlet, the green blinked but only for a couple of minutes and again red. You have to take it to a service center. And unfortunately there are only 3 of them and they are located in the city center. In general, the purchase is satisfied on the one hand, but disappointed on the other.
