I bought it after searching for something more affordable than the lead torque screwdriver. I wanted a range setting between 10 to 70 inch-pounds and this unit has it. It also contains a set of bits in the hard case and it can easily hold aftermarket bits as well. My only complaint is there were no instructions provided with the kit, but it's simple to figure out. Even a link to a YouTube instructional video would be worthwhile for the novice user.
