I have a similar Dewalt model which converts between inline and pistol grip. Best thing since sliced bread. I used it to remove a kitchen's worth of cabinet hinge hardware and reinstall it after painting and it was still 2/3 charged afterward. Good torque and you can turn it manually to snug up a fastener. Simple torque setting mechanism.
It is one of the most ergonomic and intuitive tools I have used. I have two.
