This is the ULTIMATE electric screwdriver for small, delicate screws and models. I use them at work to build drones where stripping a screw is not an option. The adjustable torque settings combined with the super intuitive gyro screw action means that you can feel the threads engage and slowly torque them down the perfect amount every time without stripping anything. It has fully variable speed, not just an on-off switch like the cheap ones. The variable speed is KEY to not stripping screws. It literally is like a rock crawler screwdriver with super slow speed and precision torque.
I much prefer the pistol grip. There is a version that you can switch back and forth between inline and pistol grip:

It is completely worth the money and then some. I own 3 and keep them in different places so I always have it ready because its so useful and such a TIME SAVER! Seriously, no one has time for Allen wrenches.
It also has a cool saddle back thing that holds two extra bits so you can keep it loaded with all the stuff you use most often. A+ would buy again!
