I think this toy is one of the most valuable, which have ever seen. Graphical programming is structured awesome and you can deal with program and data flows, without having to go straight into the depths of the text-based programming. The program modules are self-explanatory and you can get quickly the features you get when you selectively only individual sensors or motors anklemmt and their reactions to the testing program blocks. We have driven the NXT at the moment about the Bluetooth interface, which is very pleasant, because you can avoid cable clutter. The toy is also very fun. My son was bitten by the crocodile when he accidentally the distance sensor coupled to the motor for the mouth.
Overall, one can say that the NXT 2.0 provides an incredible number of opportunities and encourages creativity in the technical field. So far I had only seen almost toy that promotes consumer behavior. Money is the NXT always worth and the internal microcontroller are those with whom I work in real life. I'm curious what I can even tinker it.
The durability only got 4 stars because the Gear Unit of the three engines already has a small damage. My son had mindlessly driving by hand vigorously agitated and this need of some gears probably a few teeth have erupted. Is not quite as bad, and the use was also no purpose in accordance with, but a bit more robust, it could have been. Luckily, you can buy more these parts separately, about 25, -.
Strong buy recommendation!
