"I received this as a gift for my birthday and had a good enough time building it. I was shocked it needed 6 AA batteries to use but thats minor as I enjoyed playing with it but not enough to permanently devote all those batteries to it full time. My personal beef with it is the high price for the small amount of pieces the set contains and ease of the build. While i'm grateful for the set, I personally would have recommended spending the money on a different set."
