The background video certainly grabbed my attention. And wouldn't let it go!

It would be great to have a video showing the principles behind the product but the video as it stands is too distracting. It zooms, scrolls or switches view every one to two seconds. I didn't think I'm slow, but the current video the switch from user-focus to screen-focus is too quick to get a feel for what's going on.

Maybe slow it down a bit or stick to one or two key video angles?

Just focussing on one point. Apart from that lots of other good comments here.
