Hard to Assemble, Poor Function

My son loves marble runs. We've built a half dozen different sets. This was, by far, the worst. The instructions were hard to read and the assembly was difficult and unforgiving. When finally assembled, the elevator never worked. It had to line up completely perfectly, and it just doesn't. Wasted almost half a day putting this together. Very disappointing. I would not recommend for anybody at any age.

Was not as fun.

The instructions were difficult there were a lot of pieces and no clear way to construct the maze. I would definitely never buy one of these again. Definitely too difficult to build with an antsy 6 year old.

Great Toy set for a child that Fidgets(Teenager)

I received this about a month ago and I absolutely love this set for my son. My son has a hard time concentrating in class and he always need something in his hand in order for him to do his work. Even though this is a sit where it deals with magnets, I do see that he is more relaxed and he can focus a lot more with these things in his hand. His mind is constantly going and he absolutely loves to build. This is great for him to work his mental muscle with figuring out how to put things together. And I Absolutely love the fact that I even got this for him. Highly recommend it for anyone who does this for their child

So much fun!!!

I’ve never built a marble run in my life until I got this set, it was surprisingly easy to build and conduct the marble run, I did it with my children and we had a blast, definitely a great idea for a family night
