Why, oh why, can't I find a laser pointer that lasts more than 5 minutes!? And it doesn't matter whether it's cheap or expensive...it. just. doesn't. LAST! Does anyone have a laser pointer that they recommend that lasts more than 5 minutes? And it's not always the batteries. We've gotten laser pointers (usually the more expensive ones) that have had extra batteries. When the pointer died, we would replace the batteries. Again, five minutes later...death of laser pointer.
