They have a dedicated site now with their own forum.
www.lasersaber.comThere's a dueling vid right on the opening page. Also a message (from August) that a sound system is in the works.
They say the ladderup and down is done with a magnetic attachment but that just doesn't look right.
Any strike hard enough to dislodge the magnet is going to dislodge it while dueling.
I wonder if they've replaced the magnet with a vacuum system.
The laser pointer installation looks like a pretty tightly sealed system and the hilt shows two buttons -- one might be an air bleed.
Open the bleed and the slider is free to travel. Close it and air pressure keeps it stationary.
That's how it looks to me anyway.
