National Geographic Marble Run with Motorized Elevator - 150-Piece Marble Maze Kit with Motorized Spiral Lift, 30 Marbles, Storage Bag & More, Perpetual Motion Machine, Marble Game, Kids Physics Toys

Bought this for the little... ended up hogging it. The motorized lift adds nonstop fun, and the pieces are sturdy and easy to snap together. It’s educational, but also wild fun to watch marbles go on their rollercoaster adventures. Science + satisfaction = 5 stars.

Good quality and fun for kids

The media could not be loaded. This is so fun! My 5 year old son got this for Christmas and it loves it! One box comes with plenty of pieces to make a really cool intricate track for the marbles. We even figured out how to make one with two different tracks. My 5 year old is able to make some little tracks by himself but he prefers when me or my husband help to make a “bigger cooler one”. So, some adult help or older sibling help make be needed for younger kiddos!

We'll start with that -most- pieces are quite strong, made of a bit of a thicker plastic. They're larger than some other marble runs (we have two other sets), and they aren't compatible.Bonus points: DOES fit 'normal' size marbles (we bought the tiny of varying sizes, and it fits the regular).Negative points: Hard for littler kids to do themselves, as the pieces just won't stay together and the more you mess with it (even with proper stabilization and pushing them hard together) it pops apart very easily and can get EXTREMELY frustrating when you've got a good build going and the pieces further back are just popping apart and falling to pieces. As multiple kids try to play it just crumbles, even when solidly built.The parts to the elevator are EXTREMELY sensitive. Kids were putting them together and the little tabs snapped right off, so now the entire elevator is gone (as without the little gray spinners, it's useless).Overall, it seems worth the purchase as it is fun to play with, the design of them overall is nice, and there is a nice variety of pieces with different curves, spinners, etc, but this set is INCREDIBLY FRUSTRATING! If possible, I'd recommend other more sturdy sets, as this one seems more set for small builds and not extended, but it will give you a little bit of fun before you get too frustrated and walk away, because it crumbles too easily lol.

GrandKids live this marble run. They work together, and laugh... it's fabulous!

Plenty of options on how to assemble the marble run. The only complaint is it would be nice if they provided instructions with a few options. When my son saw the box, he wanted what the assembly on the box which was hard to follow/create. Have a few options, similar to what Magnatiles does would be helpful.

Very educational and fun to play

Fun! But very frustrating as the pieces you build will NOT stay together. I was so excited to do this with my grandkids but we had to quit after 20 min or so of trying. Loved the electronic lift part. Think I may glue it together in certain areas and see if that makes it stand up better.
