This kept my son completely engaged for 2+ hours many times. He had to learn About following directions, Hand eye coordination, failing and trying again, and of course creativity. It was mostly something we did together but I know certain kids would excel it on their own. Even now at 9 years old he'll mess w it on occasion for his younger sister.

This is my go to gift and they love it every time at birthday parties!

This has been a hit with my students. It has a booklet that the kids can follow along but some of my students have started to build their own design. It is neat to see their imagination flourish.

a high quality marble run that is worth hours of fun. My kids love this, and the piecies are made to last.

Probably one of my most used centers for choice time in kindergarten. I Didn't think that it would get as much use, but it always seems to be the center that is filled and its a great price when its on sale.

I am not sure if my 7 year is old is just lacking creativity but he can never seem to build anything that's a cool enough course (in his words). He tries his own routes and options but never seems to enjoy this more than 5-10 minutes. He followed along to some of the obstacles that were provided to try but he frequently gives up.

Easy to assemble pieces are durable high quality. Highly recommend!

This is such a fun toy. My child's older cousins are able to build this much easier than my younger child can, but they all enjoy it. Keeps them busy for a while.

Very engaging, cognitive and good quality set

Both of our Grandsons love this marble run !! We are purchasing the small marble run for our Granddaughter.

Great fun. Grandchild loved it and grandma and grandpa did too.

My son got this for a birthday present yesterday and we have built the switchback (medium) and marble mayhem (hard) tracks. Both required more than one person to assemble and during assembly the connectors kept coming apart. The end result is not sturdy and both boys can easily knock the completed track/tower over. There are some quality control issues with the connectors. I'm very confused by all the other reviews saying this is a sturdy product.
