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 it for the young daughter of a a friend. She is 2. I read the instructions wrong and it is geared for 8 year olds. She is smart and dove into it anyway, as hoped. Excellent, fun, educational toy. Easy to learn

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.

My 7 year old grandson loves this. I feel it could be a bit sturdier, but no issues when he is playing with it.

Basically it is good, and our 6-year-old grandson had a great time with it. However, be forewarned. I bought it because of how many pieces it had and pictured this massive structure with marbles runs going all over. However, there is no way to do this and use all the pieces at one. First of all, the mechanized tower is only so tall. Secondly, to ensure that each marble carried to the top is able to travel down, each part of the track has to go progressively lower, which, of course, limits how many pieces can go in a run. Having so many pieces then is NOT to make one big run, but to be able to change it out into different combos. Also, it is somewhat tricky to get more than one run going as they eventually have to join before going in the bottom of the tower. It is fun and works well, but it might have been good to know before hand. I might have bought one with lesser pieces if I had know. It might be nice to have an option to extend the tower higher which would increase the length of each marble run. It is also a little more complex than I thought. Younger kids might need an adults help.

We love this product! Was expecting it to be a little bigger but very satisfied! The educational value of this exceeded my expectations! It is very durable and a variety of colors! It was a little expensive for the product but provides hours of entertainment. It has so many different functions easy to use for anyone. Would highly recommend.

My nephew loved this gift!

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!

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.

Me gusto muho que este producto permite desarollar la creatividad, entender principios de mecánica, así como también ingenieria civil por las estructuras, fue divertido armarlo junto con mi hijo, es todo un reto a la imaginación hacer caminos que puedan terminar en donde uno de desea, muy emocionante este juego. recomendado para niños mayores a 10 o tal vez 11 años

My son loves this stuff he has hours of fun changing tracks around and making me come watch lol I love it
