Marble Run Coaster 55 Big Elements Kit. 40 Building Blocks+15 Plastic Marbles.110 Tracks Length Genius Fun Set Learning Railway Construction. Classic DIY Toy for Family

My 4 year old loves watching the videos on YouTube of other kids racing marbles so we got him this set so he could race his own. Its not really the marble race set i was looking for but it still pretty cool. It can be a little annoying if your kids wants to move it or is a little rough or excited playing with it the pieces will come apart. I would suggest leaving it one spot after put together unless you want to change up the design or have older kids that might like changing it up a few times. Over all my son likes it and has fun racing the marbles

As a Mom, I know my sons always enjoyed their marble run toy. As a pediatric Speech-Language Pathologist, I have shared this toy with my "friends" and can say, generation after generation, it is always a winner. And, these newer sets allow you to view the "action". Thank you for your prompt service of this fun and engaging Marble Run Coaster! https://www.amazon.com/dp/B01B4Y5NWK/ref=cm_cr_ryp_prd_ttl_sol_0

Great toy! This purchase was an add-on to a set my grandson already had. He was so excited when he opened it that he ran to me to give a hug! After opening the rest of his birthday gifts, this was the first gift he and 3 cousins played with.

Great product , as described ,arrived quickly.

Too much fun, go straight for the 105 piece set.

Very entertaining for my Autistic 5 year old great grandson

So much fun, keeps my son occupied more than any other toy. He's three. Just wish it were a bit tougher material.

Fun to play with.
