Joyfy 170 Pcs Glowing Marble Run for Kids, STEM Construction Building Toys with 5 Glow in The Dark Glass Marbles, Christmas Birthday Easter Gift for Boys & Girls 3-5 4-8

I was a little leery in purchasing this due to some of the reviews, however, I'm glad I did. I bought this to entertain my two great nieces when they stay at my house. They are ages 10 months %26 5, and they both enjoy playing with it. My 13-year-old son and his dad set it up, and my son even enjoys playing with it. I am able to pick it up and move it with no issues, and the pieces fit together just fine. I also like how colorful it is and that it came with several marbles.

This has kept my toddlers attention longer than most toys. He loves helping put together the runs, and enjoys watching the marbles roll down the track for hours afterward. Currently he needs help putting the track together but I imagine in a year or two he'll be able to do it by myself. Great toy for any child 3 .

My 2 year old son received this for Christmas and out of all the toys he was gifted this one was by far his favorite. Although he lost most of the marbles that came with it he absolutely loves playing with it and watching the marbles go by. I help him build the trails so he puts the marbles in. It's easy to assemble in a whole bunch of different ways. Keeps him entertained for the whole day! It definitely exercise his brain.

It is a little harder to put together than I thought, but once put together its great. Not as stable as I thought with younger kids it can easily fall over so you know. However it will be great building skills for a 6 yrs and up. Under 6 the child will definitely need help. I bought it for my 3 year old grandson, and now for my 7 yr. old grandson again. The nice thing is if they like it, you can buy 2 of them and build a much bigger one. Great for family time. And if you have a place where it can stay in a place without being broken all the better

I was skeptical about this toy for a inquisitive 4 year old who loves to play with STEM toys. This was the most favorite gift. She was absolutely mesmerized by it. She took it apart and put it back together in a different configuration. I highly recommend and would buy it again.

I oved the fact that my kid s able to assemble and take apart easily, some of the pieces do break a bit easily., they need to be reinforced or thicker.

I bought this marble run for my grandson for his birthday. He is now in his early twenties but he has autism, so I thought this would be entertaining for him. He was delighted with this toy and his older sister even joins in to play with him. I would recommend it for a fun time.

Very nice product however instructions were not that good though took a little longer but it's all good

Well I haven't actually opened it yet but the packaging does not scream “premium product”. You can see in the included picture that it has grammatical errors and seemingly random clip art on it, including one that just reads “3D Text”. It's a simple toy and it's probably going to work fine, but if the quality of the packaging matches the quality of the product, I may have made a mistake.

Good set and works great completely on its own, but try to combine it with the same brands other sets and you will be disappointed as they're just slightly a different size, meaning they won't connect together. Only reason I bought this set was to combine it with the other we have. Had already returned another set which didn't even have the same size marbles, so decided to keep this one only because they are slightly compatible. More communication/transparency from the company would have made these issues avoidable.
