Raventrack Gravitrax Magnetic Cannon Accessory - Revolutionary Marble Run & STEM Toy | Perfect for Kids Age 8 & Up | Compatible Accessory for 2019 Toy of The Year Finalist Gravitrax Set

These are perfect!!!

We love the gravitax series of toys. It keeps my boys busy for hours. You can buy the base pack and then add on infinitely. It is a great gift for birthday parties as well.

This accessory enhances an already fun marble run

Very cool. Gives the marble a boost as it slows down. Allows you to make larger tracks.

Purchased this for my 8 year old son who loves building and constructions toys. He thought it was the coolest thing ever. Lots of different pieces and plenty of pre-designed tracks to set-up. So its similar experience to LEGO but with more fun payoff after the build. He had a few friends over and they all enjoyed playing with this for hours. Great product! We also got the expansions. This was their favorite expansion, the magnet launcher is very powerful.

Though I purchased this for my 10 year old grandson, my 6 year old grandson LOVED it more! It's a bit difficult to set up and the marbles fly off the tracks too easily. We made a couple of the runs and this happened with each one. Great for thinking. Not easy for a crowded Christmas with all it's confusion and clutter.

Awesome accessory for the Gravitron. If you only buy the basic unit and one accessory, this is the one to get. I do think it is expensive for what you get...comes in a large box, but really adds zip to your creations.

My 11 yrs old loved it. He spends hours on it, it so relaxing to see those marble going and arranging different ways! Good idea to keep them busy without electronics when they have 3 weeks unexpected Covid break!
