I just bought 3 lasers. The website description recommends for use on ceiling, walls and dance floors. The manual rates the laser as 3R and states that it is illegal and dangerous to project on people. Aren't people supposed to be on dance floors? Every laser product this well know company makes is 3R. It is hard to believe that there aren't 1000's upon 1000's of this and similar units installed over dance floors in clubs and venues all over the country. Something does not seem kosher here.
