Marble Run, 224Pcs Marble Maze Game Building Toys, Upgrade Marble Track Race Set & STEM Learning Building Blocks Toys, Birthday for Boys Girls Aged 3-12

I love this marble run. It comes with three bags of marbles of different types. All the pieces are well made and high-quality and durable. Assembly was fairly easy (if you're making the contraption on the box). The instructions are easy to follow, but I feel at some points they were incorrect. If you follow the pictures, you'll be fine. The elevator itself is a neat idea, but I had problems with the chain wobbling and knocking balls off. I tried to increase tension but I could never get that problem fully solved. But other than that it worked about 95% of the time without knocking the marbles down as they're going up. My kids loved playing with it, and that's all that matters. I can't wait to make my own marble run setup as there is so many pieces. I wish I had this as a kid.

(this review is part of a promotion) I received this $224 piece marble maze game run with electric elevator and it is so cool takes a few minutes to put together but rather simple instructions electric elevator is something I've never seen before put the marbles in the top they run down they hit the elevator the elevator scoops them up and take some back to the other side at the top and then they run down that side and come out the bottom it is too cool since I put it together my little one has been playing with it for hours absolutely loves it it's really awesome seems to me great quality plastic it's a good product overall I would definitely recommend.

This marble run was great, kiddos played with it for hours after they built it. Construction is easy, plenty of marbles come in it. I wouldn't recommend for kids young enough for the marble to be a choking hazard. The instructions were easy to read, and it was fun for them to play.

Very nice toy. My kid LOVED the elevator feature, it's really cool! The instructions were complicated at times, but if you go slow %26 make sure every piece is correct the mechanics will work. Definitely kept my kid occupied for a long time!
