My 10 year-old saved all his earnings from mowing lawns to buy the Lego NXT Mindstorm and has been impressing me daily with what he can do with it. We had to order another motor because 1 did not work. Amazon was great and replaced it. My son has built a tank, a cobra, a guitar, an alligator, a catapult, a car that follows lines or colors. The guitar amazed me the most because it was so unlike all the other Lego toys you can buy. And he built it himself!

The lEGO NXT motors are what they are.. you would not be reading this if you did not already have some and want more.
As far as I am concerned, being able to purchase these in loose weight, is about as cool as it gets, I can not leave some on projects while working on other ideas. = Happiness.!
For LEGO rotation movement, these are the ticket.
