The absolute worst! Paid for a headache and only minutes of fun before packing it up to return it. Also false advertisement as not all 3 possible chutes work simultaneously; you can only have two working at the same time. Worst instructions I’ve EVER seen. Target should cut ties with this manufacturer/distributor.

Horrible instructions that make no sense. Save yourself the headache!

Our son is obsessed with marble runs and we probably own 15+ different types/brands at this point. Hands down this is the worst quality, most frustrating, and most expensive one we’ve ever bought. It was uneven even when we followed the (terrible) directions exactly. Taking it back.

This marble run is awful. Directions are not clear how to build. Structure is not steady and frequently falls apart when playing with it. Next time will super glue the pieces together

My 9 year old son loves marble runs, I’ve put many together, none are ever easy, but this one is a nightmare. The instructions are basically worthless and I’ve yet to get this thing together properly. #frustrated

Cheaply made. Instructions don't make sense. Doesn't fit well together. A waste for us

This product is not intended to be built an sturdy enough to make the “designated” design. However this could be used for free play an creative building . Horrible puzzle. Also I wanted a marble run not a puzzle. I would not purchase again and regret not researching more into the reviews

Absolutely impossible instructions. The most frustrating toy we’ve ever put together.

Directions are horrible. How is this for 4 and up when it took my husband over an hour to figure this thing out. It was fun in the end for the kids though

The instructions are not helpful. Not age appropriate for a 4 year old.
