people use l@ser from the other massive thread on pprune about these idiots, because when people use laser the google ad's that show for some poeple on the pages, which trawl for keywords then display an ad based on the keywords it finds, and has been displaying ad's for laser pointers. Alot of people requested that others use l@ser so that anyone who is reading these threads for ideas wouldn't be linked to where they can purchase some very powerful pointers.
