Working on this 3D puzzle has been a therapeutic escape for me. It’s challenging, yet relaxing, and I enjoy the process of building something from scratch. The finished product is a beautiful addition to my home decor!

Tried to finish it, but a few pieces were missing .

This thing is not for everyone, but if you plan to spend hours with your kid to put this together, it is lot of fun. Pieces fit together nicely. We used provided filling tool generously to help. Overall, very good to spend quality time with kids.

The construction was VERY detailed and good! I've done approx 10 wood marble runs,and this was tops. Whis it was bigger

This is a marble run that is worth buying. The parts are fully equipped, and the matching files and wax blocks make the assembly process smooth, and after the assembly is completed, it can run smoothly without jamming the ball.

Poor quality parts. Too fragile to work with. No customer service

I had been wanting one of these machines for a long time and finally splurged. I ended up putting it together myself and it wasn't too difficult.
