iHeoco Marble Run - 131pcs Glowing Marble Race Track Toy for STEM Learning - Marble Maze Game - BPA Free Educational Construction Building Blocks Gift for 4+ Boys Girls (Incl 4 LED Glowing Marbles)

I got this for my six year old grandson but it was difficult to follow the plans and to keep it together, both for him and me! It was wobbly and sections easily fell apart even on a flat sturdy surface. It’s difficult to re-connect a section that comes apart without disconnecting the neighboring runs. It would improve the sturdiness to have bigger “feet” holding it up and to have more solid connections. It was frustrating to take the time to set it up and have it so easily fall apart regardless of how tightly the pieces are connected together.

The maze is relatively sturdy. Two of 4 lighted marbles would not light up. My grandson enjoys it, but the maze falls apart all the time, so he gets frustrated because he is too little to fix it. Marbles get stuck at the wheels constantly. I'm not happy with lighted marbles as the cannot be open and fixed, and i have only half of them working.

The kids assembled and played it in a party. It can be assembled in a variety of ways and changing them around. The boys and girls arranged from 5-11 yr old enjoyed playing marble run for a long time. It is sturdy and no broken pieces after the party. It is fun and educational.

Not only did my grandson love it, but his dad got into the act with him! They really enjoyed this toy and I would definitely recommended it.

This toy is a great help for the development of children's qualifications. I bought it for my son's friend and he liked it very much

Super neat toy and glows in the dark. My daughter saw this and had to open it right away. Hours of fun.

This is a pretty neat toy, but 2 out of the 5 light up marbles didn’t work upon opening the box. I emailed the company and my email came back as undeliverable.

Loved this for my 3 and 8 year old. Unfortunately one of our led marbles did not light up but still a great toy.
