The backlash of the acc-ra in the drill is less than a millimeter. There is no beating of the cartridge. The reverse switch button is a little flimsy, I won’t hammer nails with it. Its pros: Powerful. Very neatly made. Good balance. Illumination at the right spot. Fits well in the hand, incl. and female (the wife sometimes likes to twist something) Cons below: Just a huge and stupid suitcase. Expensive.( Non-switchable backlight. If you often screw in small screws, then this screwdriver will not work. Even on minimal effort, it is too powerful for them.
