I actually had this thing. It was pretty cool, but you could only play it indoors. If you took it out in sunlight, you couldn't see the little red dot, but you could see the mechanism moving inside. I know it looks goofy and dated now, but this shit was awesome in the days before everyone had an Atari 2600.
It still worked when I sold it at a yard sale some time back in the mid-1990s. I was kind of surprised at that. I'd found it buried in a bunch of my old junk, popped in some batteries and it operated just as well as the day my folks had bought it for me.
