The only reason I wanted to watch this video was because I wanted to know what this thing did. Still don't understand it. I can move and resize regular prims too. Align them easily and rotate without any gaps. Without the prim being highlighted and flashing. I don't get this tool at all. Why should I buy it?! Why should anyone?! Don't get mad at me for being honest. it might be a good tool. But that's the reaction of a person, who sees this thing for the first time. And NOTHING unusual was demonstrated in this tool's description, nor in the video.
