I bought this mindstorm lego kit for me. In fact, it is a true family game because my children love to robots (especially my 7 year old daughter, but his brother and sister from 5 to 9 also love). The assembly is very well explained. The programming is more complicated for the children and I have not taken too much time to show them. A box of course a bit expensive but very good value for money in the end when you see the number of things you can do with!
