I didn't watch all of that video, just snippets. I'm sorry but what a waste of time. Every application I saw was easily accomplished with tools that come in a $30 starter's tool box.
The most frustrating being the handle on that glass door....so much harder than it needs to be!
And at point in the video, I realized a flaw not mentioned yet in that there are possibly too many connections &/or adapters.
I do see if you weren't able position a screw driver straight on, but there are already adapters for the few times you would need. The only think that makes sense is if it has a gear multiplier of 2x or 3x speed.
A few of the examples did show that maybe it was easier to break a fastener free with extra leverage, with the lug nut removal being the best example, but at the same unrealistic. Even if this is for the home gamer, they probably have an Impact wrench to do work, and that adapter will likely not hold up to tightening the lugs manually in my opinion.
A few examples showed turning the screwdriver was faster than a ratchet. That may be true, but I don't know any handyman not using an impact driver to take out door hinge screws, we are not Amish. Though I also wouldn't be taking hinges off unless the door was removed already.
Just a heads up, I'd think about finding some generic non-copyrighted music for the background, or foreground, music. You may lose your *** in a lawsuit over a tool you haven't did yet. Not really, YouTube will just mute the audio
