yes. DON'T buy blue lasers - red and green lasers on moving patterns are fine but with the blue ones even momentary exposure and sometimes reflection alone can cause permanent damage depending on power output. green lasers under 10mw are okay as long as they are in constant movement. prevents more than a second's worth of direct exposure and the customers tend to complain less.
