This was a Christmas gift for our five year old Grandson. He is very adept at building intricate complicated marble runs, since he was 3. Bear in mind GraviTrax is recommended for 8 years and over. So if you are buying this for a child that isn’t used to building tracks remember what age it suggested for. My grandson found this challenging at first owing to the complications of building the track. (remember he is 5yrs old) He had a little help from his parents to start with to encourage him. However GraviTrax is a super building set for budding engineers, it gives my grandson great pleasure when he has spent hours building and getting the track to run the marbles. GraviTrax is a good quality, medium priced, toy/activity for children, with plenty add on sections to purchase. In this day and age of tablets, video games, iPads etcGraviTrax is a super building mind taxing set.

Macht Spaß.
