Wicked Lasers Given Reprieve by LucasFilm on Lightsaber Clone
The letter, from David J. Anderman, General Counsel for LucasFilm, stated that based on the publicity and statements that Wicked Lasers had made, it was clear that "The media and public has come to realize that Lucasfilm would never endorse or license a highly dangerous product such as your Arctic Pro Laser."

Wicked Lasers CEO Steve Liu said, however, that all the publicity proved to a positive, and sales in fact tripled. "This has been strange. We felt that it would have been a very bad thing in the beginning, but it ended up helping the business in a very big way."
