Doing it in a lab like in the video is easy-peasy. Try doing it lying on your back in half-darkness and freezing cold inside a cramped sarel box, and see how easy it is.[/color][/size][/b]
Oh, of course. The demo is not the install.
It's just that once you've got the wire into the hole, pressing the "connect" button is going to be a bit easier than finding the hex key, tightening lightly, swapping to the torque wrench, getting it to grab, and then torquing to spec. All the other parts are roughly equal in shittyness for all cases.
