"I love everything LEGO....EVERYTHING! My son and I get all the Batman sets, when I saw this one I figured it would be easier for him to play with (he's almost 4). Everytime you touch the Mech something falls off, then while putting it back on, something else falls off. I have never given an even sort of bad review before, but I almost feel obligated for this one. It looks cool, but if you're getting this set with the thought of playability, buy a different set, because this one isn't it. Poison Ivy doesn't have the best balance either. The minifigs in general are nice, but man the mech is a stinker."
