I'm guessing he won't get too much longevity out of either the batteries or bulb, but if he's just using it as a toy "cop flashlight" to temporarily blind himself and others... more power to him.
P.S. Don't those Duracell Ultra CR123 Lithiums sell for around $4 each - not $4 for three of them? That would make it a $15-20 flashlight, still cheaper than a Surefire though.
