Kid Marble Run Building Blocks with Elevator Spiral Lift - STEM Toy Bricks Marble Maze Race Track Set with Motorized Elevator, Big Blocks Educational STEM for 3 4 5 6 7 8 Year Old Boys Girls

Hard to put together

This is a gift for the Grandchildren and they love playing with this toy, it builds great hand and eye coordination with fun racing each other. Please be careful to not give this to small kids since everything they like to put in their mouths.

The ball elevator does not work properly; the ball(s) would get jammed on top. Very frustrating after spending hours putting it together. Have to return it. I gave it a one star only because the rest of it seems well made and is very colorful.

Way cool fit my grandkids. Easy to put together. Entertaining

It works well, but my kids had some trouble following the instructions and I had to take over. Also, you can't do a creativereworkof the configuration, so the kids get frustrated. I liked the idea of it being compatible with duplo, and it is, but I should have gotten something stand alone that would be more flexible.

Bought for 3 year old grandson and he loved it.

My 6 year old loves this. Need adult assembly. It is not an expansion of the duplo marble run sets. It's like a set system on its own. However minus the ramps, the blocks are similar. So keep that in mind if thinking it's an expansion.

After putting this together for my 3 year old grandson. Who did not like the amount of time it takes to do this. When it was all together the middle spinning ball carrier did not work. He wanted to play with it and was so frustrated with it. Took it apart and it would spin a little but as soon as you connect it all together it would not work. I returned this as I was so disappointed. I eoukd not recommend this at all. Not even for older kids.
