Yeah, it did well in that video, but he's testing the tolerances of it, I don't recall he drop tested it. The issue is the way that the bit holder is designed, where it uses thin pieces of plastic to wrap around and hold onto the bit. There's just not a lot of support when the screwdriver hits the floor and all that force is now on the thin plastic.
For $70 the product should survive a 1000 falls from the top of the elevator dude's hoistway. The LTT Screwdriver isn't a bad product, it's just extremely overpriced and not intended for anyone except a limp wristed computer nerd who will lay it on a satin pillow after using it to install their motherboard.
