JOYIN170Pcs Marble Run Premium Toy Set, Construction Building Blocks Toys, STEM Educational Building Block Toy(120 Plastic Pieces + 50 Glass Marbles)

I bought this for my grandson's 4th birthday . It needed some adult help to put together as the pieces are very well fitting . I don't know who had more fun watching the marbles go down , my grandson or his parents and grandparents . It is certainly a plus that the pieces are clear unlike some other marble runs . It is very sturdy and doesn't fall apart if moved carefully . I would certainly recommend this run , it is the first toy my grandson plays with when he gets out of bed

A decent quality set, with plenty of different pieces to keep it interesting. Good price for what you get.The glow in the dark marbles are a nice touch, and work well with the clear marble run pieces.I bought this to expand an existing set (from a different manufacturer). Thankfully, the two fit together with no problems, and we now have one huge set.(I suspect many of the different marble runs on the market come from the same factory)

peaces are a bit loose

Very satisfied with product and service. Thanks.

Comes with lots of pieces to build various marble runs. My 7 year old loves it

Sturdy, fun (but noisy). The best bit is it’s see-through so you can track the marbles on the way down.

The media could not be loaded. My daughter loves this marble run.I had fun building it lolBrilliant

Started well but after a few months of use, the quality is really starting to show.The plastic seems to be breaking very easily on a lot of the parts, particularly the parts with moving pieces.The only brightside is that it is getting easier and easier to put everything back in the box after use.I would expect to get a lot longer out of something costing this much money.
