Title: Fun, Educational but..
Review: My son really likes the nxt, you can make lots of different things and the programming is pretty straight forward, my son (10) picked it up right away. The only major drawback is durability of your creations. It is the same program I saw with other lego systems with motors, they fall apart on the third step. when you creation start to move the lego blocks are just not very good at staying together with each impact..so they don't. So if you are looking for a long term creation don't use this, but if you want you son to have fun making and breaking, have at it!
