Saw one at the store, had a quick laugh, set it down immediately. The thing's absurdly tiny, as has been mentioned before. I can't imagine how it could be used in any useful way, even by someone very short.
My other hobby is actually modifying Nerf type blasters. This one is actually pretty good, yes, it's a blatant knock off of the Spartan Laser, but I had to chime my two cents in and defend it. Not everything in the world that is Halo related is used just for Halo Prop making. :3
