That's a cool toy. It looks and behaves like the movie prop it's based on.
When I was a kid, I always found the light-up plastic toys that make "pew pew" sounds with shitty speakers to be extremely obnoxious. What I would have given for a Star Trek phaser or Tricorder that actually looked like the ones from the TV show.
I would call this guy a loser, but I have a gas blowback pellet gun made to look like a Beretta, and how is that really any different?
