Interesting, it reminds me of something that I would have seen advertised in a Popular Mechanics mag. in the early 60's, except that there were no cordless drills in those days.
Something smells. $149 preorder? What they show in the video would cost too much to make any money on. Maybe in mass production, but who would be a fool enough to invest in that!
Regardless, a good way to wear out an expensive drill motor.
