The author has taken care to use parts of different colors so that we can visualize how the parts are assembled. Visually, it is very clear and pleasant to visit.
There are a multitude of small technical construction quite fun to build. It's great fun!
The only criticism I would make is that the author uses in its technical lego models that are no longer sold, and it is somewhat difficult to obtain.
In all cases, it is better already have a good assortment of Lego technic to appreciate this book.
Then I suggest you still buying 3 pounds because it is worth a look.
