Review: Great for little engineers in the making. - 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 etc GraviTrax is a super building mind taxing set.
Review: My newphew is so happy with them! - He now has a large collection of Gravitrax! He lives playing with them, a great alternative to lego for young, inquisitive minds.

He now has a large collection of Gravitrax! He lives playing with them, a great alternative to lego for young, inquisitive minds.

### ⭐⭐⭐⭐ Fiddly to set up but does work (somewhat)
*by A***R on 15 January 2024*

Impossible for my 6 year old to incorporate that piece into his usual set up. With my help we get the catapult to work. Not managed to finish it off so it carries on working after being catapulted as yet but maybe requires more practice on our part.
