Vast improvement on the old one that came out when I was a kid. And I love how it works with Technic type pieces as well. But not worth the money to buy one. They are coming packaged with so many sets at the moment you're better off just getting one that way. I ended up with so many I was giving them away. In short get your hands on one, but just get a cool set that comes with it already. Because every Lego fan would really want more Legos to use it on.
