This has to be the best present I bought for anyone. We have all had so much fun with it, the creativity to work out new runs learning to do small adjustments to make it work, it's been brilliant. We struggled getting the hang of the Catapult but that's just us, only downside is not being able to buy add ons. I wish I'd bought the bigger set but well will just have to get that next. Highly recommend this. Also we have used an old wipeboard rather than the fridge which has been perfect especially as we can move it around Review: Fun and educational - Educational and doesn't take up space on the floor. Comes with a travel bag so you can easily take it to someone else's house. Pieces are sturdy and the magnets stick well. Instructions were easy to follow and encourage trial and error to get the pieces exactly in the right place or to make your own design. ## Features - Warning:Not suitable for children under 10 years.

It is located on the bottom left-hand side of the additional photo column. **Q: Can you connect this magnetic run with the makeway marble run?** A: I do not have the Makeway, but have several other systems. This marble run uses the fridge or metal surface it is attached to in order to hold the marble - as opposed to systems like Fridgits that completely support the marble away from the surface it’s attached to. It might be possible to create a transition from a system like this to another, but it would be difficult to have this system second. The marble would likely fall away as it only supports the marble from underneath on the outside, but supports the marble from the side on the fridge side. **Q: Can you buy more sets to enlarge the experience?** A: I don't know if they sell individual sets of extra pieces, but you could buy 2 or more of this set and I'm sure it would be even more fun. **Q: Will this cause scratches on the fridge?** A: No it won't cause scratches ## Customer Reviews ### ⭐⭐⭐⭐⭐ Best present I bought at christmas *by A***N on 11 January 2024* My son is 9 years old and we bought him this for Christmas.
