Q: I simply cannot believe that I paid $30 bucks for this thing. It does absolutely NOTHING, except make a few electronic noises. I kept poring over the instructions, certain that I'd missed something......but I hadn't!! BORING. I think that even my 7-year-old son, who wanted this thing, was disappointed. And don't even talk about the batteries...to add insult to injury, this thing takes button cells, which aren't cheap. Save your $$ for something better.DYB
A:
Negative
