MONILON Marble Run Toy, 122 Pcs Marble Game Race Track Kids STEM Toys for Boys Girls - Learning Educational Construction Building Blocks Gifts Toys for Kids Ages 4 5 6 7 8+ Years Old

I'm so intrigued by the endless ways you can set this marble maze up! It's different every time. It's like a 3-D puzzle that really gets your mind working. My 3 year old loves it but he needs assistance setting it up so it doesn't topple over, which is fine, I get all wrapped in making the towers. Oh how he laughs and dances around it when the marbles go down! I'm going to buy him some nicer marbles next time we get to the toy store-- the snap-together plastic marbles are a bit of a turn off (but oh well, they work). Also, only 1 out of 4 of the turning wheels actually turn-- I have to force the marble through the other ones so I just removed the wheels for those pieces. I also wish there were more pieces because I want to make a bigger tower.... I'll buying another one soon!

So this toy comes with over 100 pieces to make some sort of maze or obstacle course to send a marble through. Overall i feel like the toy kind of help kids create and engineer their own toy in any way they would like. This offers creativity, fine motor practice, and physics. Theres a bunch of different colored pieces and little wheel obstacles and connector things. The box it comes in is quite large but i was able to transfer it into a smaller bin. The pieces are quite small and I believe on the box says it is for ages 6+, so I would not buy this for a toddler or anyone with picca, and if it's played around a toddler I would be especially careful of them putting these small pieces in their mouth.

I purchased this set for my son's 5th birthday. He opened it right away and didn't put it down for hours. Next day he played another few hours. Construction was simple and fun, whether you follow the model's instructions or make your own marble race, it was easy enough for him to do on his own. I know he will come back to this toy frequently to combat boredom when we are stuck inside on cold rainy winter days! It was even fun for my 2 year old daughter.PROS:ValueEntertainmentFine Motor SkillsEngineering PlayIndependent PlayONLY CON:The balls are not real marbles, they are two pieces of plastic that you have to push together to make a sphere, but they run all the same.

Kids live to play with this toy! I have used It with children ages 4 to 11.

My grandkids love this. For now just fun with mechanisms and simple machines. Later plan to explore gravity, friction and inertia

Great quality and fun for my autistic toddler. Be careful with the marvels though because they are small.

We haven’t opened the box yet—it’s a Christmas gift—but the box is quite attractive and that’s good enough for me

I bought this toy for my grandson and he loves it. It engages his imagination and uses building skills that are helpfu to him. He also has to do problem solving. I do not recommend that it be near small children as the marbles are easy to swallow
