Wicked Laser's Tunnel Gun II

I had never noticed this before but if this is the 2nd model, they must have had tunnel guns for a while. There is no description but I am assuming you just insert a pointer and turn it on and it creates a tunnel effect with a spinning mirror. Am I correct? Has anyone bought one of these? I may buy one.

From what I've seen on Fuzion666's youtube, that's exactly what you do. It makes a very narrow, very long tunnel though.

Thats pretty cool, but you can also just adjust the focus to make a divergent cone passively.
