The Learning JourneyTechno Gears Marble Mania STEM Construction Set - Whirler Marble Run (80+ pieces) - Learning Toys & Gifts for Boys & Girls Ages 6 Years and Up

I bought this for my 4 year old son. It took quite a bit of time to assemble with a 4 year old but it amused us for quite a while and once assembled we had a ton of fun playing together. The price was right too especially compared to similar sets and the size once assembled is decent. Shipping was wonderful and processing was quick.

Very difficult to put together from the instructions and incredibly fragile to get it to work properly. Just another cheap plastic toy that is going in a land fill. A couple things that make this really frustrating:- The parts are not easily stuck together and taken apart, so my 5 year old isn't able to do this by himself.- Not many configurations are possible other than the 'suggested' one on the instructions- Even the suggested configuration didn't work well

Very easy to put together, was able to build it with my 5 year old. Kept him engaged and curious for a long time. I wish the moving gears actually interacted with the marbles but other than that it’s awesome, you need to keep the marbles that come with it , doesn’t work as well with diff kinds.

This set starts off strong and as it wears it falls apart fast. The build was ok, not super simple but not overly difficult. The concept is cool and it held the kids attention for much longer than I expected. The issue is it's cheaper plastic and when it started to fall apart the level of frustration grew pretty quickly. It also needs a specific marble size so not every marble we had around the house worked well. It's cool, but it's not a toy that is going to get passed down from kid to kid.

This was okay. A bit hard to assemble (required an adult) and fell apart easily when we played with it. Some of the parts had no purpose. I ended up donating it shortly after receiving it.

Loud toy, so if you have a problem being annoyed by loud toys when the kids play or your spouse does, then dont get it. I dont have a problem and obviously kids usually dont so I give it 5 stars as its a great building toy and it entertains the children for a very long time, time after time. Built well and generally stays together better that some of the other building toys.

Excelente producto!

The box says 6+. You need the hand strength of an adult to put this together. My six-year-old got so bored with watching me. The joint pieces are really difficult to get on and don't make a smooth transition from piece to the other. The marble couldn't even get to the bottom of the machine. I spent 1.5 hours putting it together and my kids played with it for 30 seconds.

Se la compre a mi hijo de 6 año y le encanta, tiene diferentes tipos de pistas de canicas así que esta es solo un complemento más.Pros: Es resistente, una vez armada no se sueltan las piezas lo que te permite incluso moverla sí que se desarme, además aprenden de algunos mecanismos.Contra: No hay mucho espacio para que el niño use su creatividad para crear nuevas pistas.

Kid at 5 might not find it interesting as its parts are a bit hard to plug and unplug. But they love rolling down the marbles once it’s done.Plastic quality is a bit on the cheap side.

It was a great toy. The child will learn to use their imagination.

My 5 year old loved this. He got it for Christmas. Shipping was also very fast.

Awesume toy , kids loved it
