National Geographic Marble Run with Motorized Elevator - 95-Piece Marble Maze Kit with Motorized Spiral Lift, 20 Marbles, Perpetual Motion Machine, STEM Gifts for Boys and Girls, Kids Physics Toys

I bought this marble run for my grandkids, and it looked like so much fun I bought one for myself too. It is so much fun, I bought myself a second set. There is one track splitter in each set, so now I can make 4 tracks and have several marbles running at the same time. Plus, when I got the second set, I took some pieces from the new elevator and added them to the first elevator, so that one elevator is now twice as tall as the other. A taller elevator means you can make longer tracks before you run out of vertical room and have to connect to the bottom of one of the elevators. Intertwining the tracks makes interesting designs that are fun to watch. I'm thinking about buying a third set. I'm turning 73 this year and I love this. Makes me think I should've been an architect after all. This is a STEM toy, perfect for inspiring kids imaginations. I wanted to add one more thing. The directions tell you to start at the bottom, but I always start building at the top of the elevator and work down. It seems much easier that way!!

Sooo much fun! Got this for my nephews for Christmas. They are 5 and 6 and they love it. Definitely should have adult supervision. There’s no one way to put it together, so it’s pretty easy to use. The pieces stick together well, and there are a lot of different pieces to make the marbles go in different directions. Definitely recommend using it on a solid flat surface like a table or a solid floor. It was definitely worth it! Thinking about getting one for myself.

Nice toy for my grandson. Keeps him thinking and he’s having a good time assembling it and playing with it once it’s together.

My grandson had several of these sets. Great for young minds to grow! Tough and lots of fun! I bought the 8 and up box. He was 4

Loads of fun for out kids, they had a fun time building with this model. It does wear in time and usage. The fit just gets a little loose, but overall a decent value for its price.

I bought this for the grandson for Christmas. He loves it! He’s younger, so he needs help setting it up but kids over 6 years could probably handle it. This is a great STEM toy. The set has bright colors, the lift is cool but may be difficult to assemble for younger kids. The set is a nice starter size and can be added onto.

Our family had so much fun with the National Geographic Marble Run with Motorized Elevator - 150‑Piece Marble Maze Kit! The motorized elevator keeps the marbles moving without stopping, and the endless build possibilities make it endlessly entertaining for kids (and adults too). It’s great for learning problem-solving and basic physics while having a blast together. Highly recommend for hands-on play and creativity!

Great Christmas gift

Il est parfait ce circuit et s’adapte à tout âge. Recommande par le neveu de 6 ans, plus que validé par mon fils de 3 ans qui utilise principalement « l’ascenseur à billes » et adoré par les copains de 9 ans qui aide le plus petit à construire ce circuit! Je valide

Hyper bien mais tout de même compliqué pour un enfant, et aucun mode d’emploi, on se débrouille !

Paid full price for a new item and received a open box. Half of the pieces are not in the bag. I am getting a refund.

Great for my young grandson,only downside,didn't help much with construction ideas,

Great for a five year old, easy assembly with a little help from dad
