I've never heard of these. You should start by telling us what they are and why they're useful. And who makes them. After 40 years of riding, I've never heard of these. After watching the video, I've no idea why these would be an improvement. Except I now need to carry a torque wrench, apparently. Please tell us why these are good, what they do for me, why I should buy them. I just don't get it. What is the advantage?

It's a locksmith company. They make locking and protection means. The advantage of what they offer is that it will be difficult for a thief to take them off without the appropriate part they sell you. very simple.
