Shaped like a chunky pen and about as easy to hold. Press forward to drive, back to loosen, or turn it by hand for the last careful quarter-turn. The 3.6 V motor is gentle enough for glasses, toys, laptops and battery covers, with more push than you'd expect for flat-pack fittings and socket plates. A ring of small LEDs around the tip lights the screw you're working on. It comes with 32 precision bits in a magnetic case and charges by USB-C in about an hour.
