I got the set for 15th birthday and am very happy with it. All other LEGO sets assembles it and that's it. This can always build new robots and programming. There are almost endless possibilities. There are also extension sets and other sensors that can be to buy later. You can build a simple robot and program or even highly complicated. The computer software is super-simple and easy to understand. The sensors, which can be to buy in my opinion are too expensive. All in all I find the product very well and I am sure that I will enjoy it for a long time.
