I bought two of these for two young boys. The only complaint they have is that the Lego (Spiderman) figure it comes with does not actually stick inside - by the usual Lego method. There is a special piece with a groove for the figurine's legs/feet to slide into; but it doesn't have the usual male/female connections to hold the figurine in place more tightly. I don't think it's a big deal, but my kids complained a bit. Every so often they'll pop off a leg or an arm, but they pop back on. I think it's a cool-looking robot.
