Product title: Thinkgeek Portal Wheatley Led Flashlight
Product description: While Wheatley from Portal might be a bit dim, the Portal Wheatley LED Flash Light certainly is not. This mighty mini is finely detailed, with movable handles. On top of the core is a button, and when you press it, Wheatley's blue eye comes to life and lights your way! Just like the real Wheatley, this flashlight will come in handy as you try escape a darkened testing facility. Of course, you'll want to be sure to have him firmly in hand should you pass by the Central AI Chamber. We really don't need him taking over the Enrichment Center again, do we? Includes 3x 'AG13 (LR44)' batteries. Ages 18 and up.
