DeWALT DCD791D2 E17EE. I'm already buying a second one. The first one has been in operation since 2022 to this day. Backlash at first brought inconvenience - self-tapping screws jumped off. The problem was solved with bits devolt. A couple of times the cartridge was tightened very strongly (barely unscrewed). Clamps if you turn the screws with a ratchet all day, so from time to time you need to unscrew the bit. A new battery is enough for 200 roofing screws 6.3 in metal 2-3mm. On the first screwdriver, the batteries are still alive, although the capacity has noticeably decreased. I also note a not very convenient suitcase - the equipment is constantly crumbling, but there is a plus: you can fasten the suitcases together with factory fasteners - an extra hand is freed. In general, I recommend!
