Marble Run Set 135 Pcs, Innovative Various Track Shape, Building Blocks Construction Toy Stable, STEM Educational Learning Toys for Kids 3-12 Years Old, Creative Gifts for Boys Girls

The build quality is fine, seems sturdy. The title is misleading, the 166pcs includes 90 marbles and not the number of pieces that form the track.In reality you get 76 pieces that form the overall track, 38 of which are small tubes that form the support poles, 4 collection plates, and four struts, which are counted as 8 pieces, and some parts of the track come in two parts and are counted as a pieces.You get 16 pieces of usable track out of the advertised 166 pcsI like that you get glass marbles, not so much a fan of the plastic ones

My 8-year-old had a little bit of trouble assembling all the pieces because the instructions were not very clear. With a little help from an adult, they were able to fully assemble all the pieces. The marble run is a lot of fun.

My 3 year old nephew had great fun with this. Good that you can change shape too

Orders this as it's a great idea for young kids, seems to be the thing on YouTube watching marble racing so why not order him a marble run game!

This was a well received Birthday gift for our grandson on his 3rd birthday. Took a while and two adults to assemble, but he has had hours of fun. Plenty marbles supplied too!

Opened the sealed box and sealed bags on Christmas Day with my 4 year old son to find that 40+ pieces were missing and the marble run could not be assembled. Very disappointed child and very disappointed mum to be honest. Returned for a refund as no other option given.

The media could not be loaded.  My 8 year old set it up and my 3 year old spends a lot of time racing the marbles down the different tracks byslherself and also her sisters too. This track in the video is constructed using the instructions that come with it but you can also make different tracks and routes for the marbles. A great buy, recommended for definate!

Out of all the toys and gifts my kids got this one was definitely the favourite! It was super fun to build, nothing missing and the colours and shapes are fun and engaging. Definitely better than the one I had when I was little! It's so strong too, its taken a tumble a couple of times but held together really well! Such a fun time even I loved it.
