I think they are cool..and annoying when they get ya right in the eyes. :/
just played a show friday and while I was tuning up (they had a couple small lasers in the back that were runnin b4 we started) I'll be damned if that son of a Biznitch didnt keep hittin me right in the friggin eye every 4 seconds. so that was annoying while I was facing my rig..
but once we started..yes , it was cool...especially with "fog/smoke" whatev u wanna call it.
then again I use a shuttle 6, so I'm kinda used to being blinded by the light.
