The Learning Journey: Techno Gears Marble Mania Zoomerang 2.0 - STEM Construction Set – Award Winning Learning Toys & Gifts for Children Ages 6-12 Years (80+ Pieces)

Was pretty quick to put together, the qr code for instructions was pretty nifty and the little one is already enjoying it.

Good quality - Worked as advertised.

Quality is suboptimal. Took forever to assemble and some of the parts broke in the process. Once assembled it was not very impressive.

My 6 and 8 year olds really enjoyed this marble run. We have owned another brand and it was not as sturdy. Once they put this together according to the instructions (it was a challenge but they were able to do it) it stayed together. I also like how it can be moved from place to place since it is on a stand! I would recommend it!

My kids have always enjoyed marble run style toys. This one looked really interesting as the pieces seemed more complex and interesting! My daughters easily followed the steps in the booklet to get it together. They love the added components of the gears and the spiral lift for the marbles. It has been sitting on our table for several days of play! They keep coming back to it! They think it would be fun to experiment with adding multiple sets together!

Very difficult to assemble and does not stay put together easily. Not worth the price. Very cheaply made.

The assembly was not sturdy, it took 1 hr to put together some parts were missing the maze was not long my 6 yr old lost interest quick.looks can be deciving. Rate 1- 10 it's a 5

Los materiales no son buenos, esta muy corto el camino, se ensambla y queda muy debil. No mal gasten su Dinero.. No la recomiendo.
