Love hate this thing. It’s hard to follow the instruction, kinda hard to see where to out everything but doable.Not very sturdy, lasts about a day and then things start to fall apart. An adult definitely has to put it together.We have built our own courses and it’s been fun to do that. But again, our 2.5 year old will bump it and basically the whole thing falls apart so we make sure she is careful. We keep playing with it so we like it but it’s kinda if a pain.

This is a nice toy, compatible with other blocks. It is very difficult for my preschooler to make full marble runs without help. The given directions for building the run on the box are very complicated and lengthy. That said, it’s a good addition to our other blocks and I’m sure my preschool will grow into it and will enjoy building runs for his baby brother in a few years.

Our 9-yr-old ASD son really likes marble runs. We bought him one last Christmas but it wasn't very sturdy, the pieces easily got knocked off. So this year we decided to try this lego style marble run. I know it's meant for younger kids but it works with the larger lego set that he still builds with regularly. He was able to put it together mostly by himself, a big bonus for us. It is a far sturdier build than our other marble run and our son likes the light up marbles. We like that he can create his own set-up by adding similar sized legos from his existing set.The only cons are the instructions are not as easy to follow as I was hoping. This caused some frustration for our son but we were able to work through it. He was also disappointed that it wont work with his regular marbles. The set comes with a few larger marbles. I guess we will have to see if we can find similar diameter marbles so he can run several at a time.I would definitely buy this set and others like it again.

Wow! Wow! Wow! EXCELLENT quality! Great thickness. Easy to put together. So much fun! Works seamlessly with legos. Hours of fun bc you can switch it up & do character voices. A MUST-BUY.

This was no picnic putting together cuz I have zero mechanical ability, but I do know how to read clear diagrams, and this diagram could have been more clear if someone took the time to do a final edit & enlarge it a bit. I had to make small adjustments to 3 areas to provide better support and/or allow for the ball to flow smoothly. It's rated for kids 3 and up (cuz of the smaller pieces), but the setup can be easily knocked down unless kids are careful. It is colorful, cute, you can't beat duplos/legos for basic quality, and now that it's altogether I'm glad I bought it.

My boys love marble runs so I thought this would be a good alternative for when they needed something different. My husband had to build it as during the building process it kept falling apart and as soon as we let the kids play it. 5 minutes later a piece fell off and soon it fell apart from lack of base structure. They are like duplos so if you have a set you might be able to fix this problem but we had to put it away for another time to figure it out later.

We have sooooo much fun playing with these. We already had some other similar blocks so this just added to it. It's such a great toy and very educational. Great for OT and development growth.

This looked really cute and fun online. I was concerned it was too elementary for my 5 year old but figured he could put it together himself since he can build with advanced legos by himself. The manual was too challenging to count “dots” and it took me two hours to build because I had to start over in several places. Also, only one of the marbles we received actually glows. There are two points at the top of the toy that are not very stable and I have had to reassemble it 4 times in the first hour of play. I cannot imagine how this could hold up with a 3-4 year old when my 5 year old is being most careful. Very disappointed.
