3in1 Marble Runs for Kids 4-8 Building Blocks/246Pcs Classic Big Blocks Toys Set Compatible with DUPLO Lego Sets/Marble Maze Race Track/Montessori Learning STEM Toys for Toddler,Kids Age 3,4,5,6,7,8+

This has been such a fun activity for my kids! It keeps them entertained for a long time and they love building different tracks and watching the marbles go through. I also like that it encourages creativity and problem-solving instead of just being a toy they get bored with quickly. There are a lot of pieces, so you can build it different ways which keeps it interesting. The pieces fit together well and seem pretty durable. Definitely a great option if you’re looking for something fun and engaging for kids in this age range! It’s a little smaller than the picture and what I imagined but that didn’t stop my kids from playing with this for hours. It was a little hard to put together (even for my husband) but once we did my 3 and 4 year old loved it

This is a mature product. The marbles spin for quite a long time in the cups/dishes/hemispheres before dropping through the center. The little track with upward-curved ends allows the marbles to move back and forth before rolling off one side. Both my kid and I like it. The last marble run that I used was made in the 1970s; this is much improved. A child might not be able to build much with it until the age of four. My kid is a bit younger than this and can combine components to make objects, but not paths. She enjoys playing with what I assemble, though.

These blocks are super fun, they are like "perbles with travel" but in construction version. They bring a lot of pieces (138 in total) and you can assemble different paths so that the balls go down. The colors are striking, they bring animal figures and they look resistant. It is a toy that entertains a lot and also helps children use their imagination by setting up their own tracks.

A good product but the box the actual toy came in was all damaged, and beat up.

I really like them My kids play the slide every day. Dinosaur eggs are really well made and fun to play ONLy thing is that instruction is very complicated.

Horrible child's toy. All the building blocks were not there and it was hard for the adults to connect the blocks let alone our 4 year old granddaughter. The stickers also did not fit and took forever for us to put them on the one apple block, thats what we think it was. Because we bought it for a christmas present in October, the return time was expired in November. Now we are stuck with this horrible toy. I will never buy from this company again.

I’m giving it 3/5 stars because of the following: 1. There are pieces that are tiny enough for the kids to swallow (I’m not talking about Lego duplo sizes, small as in half an inch in length and maybe 1/4 an inch in height?) and it’s not noted on the description. Had I had known I more than likely wouldn’t have purchased this set as I have an 18 month old and. 2.5 year old who loves to put everything in their mouths. 2. I did not know that the colored parts were stickers (such as the details on the blocks like the eyes of the animals and or their patterns) as again it was not noted on the description and I had assumed they would be printed on the blocks like the Lego duplo blocks. That being said, again, my kids love to take off stickers and put them in their mouths so this is another choking hazard and hazardous to my kids so I probably wouldn’t have purchased them. 3. Some of the blocks fit extremely tightly with the Lego duplo blocks and others are so loose that they just kind of sit on top and doesn’t not fasten onto each other. They do fit the duplo blocks just not well. That being said, I purchased these blocks because my kids are obsessed with animals and this set has all the animals they like but I only let them play with the fish, tree and tomato because the other animals have the tinier pieces which I’m saving for when they get a little older.

Easy to build for a 4 year old. Pieces are quite big so you don't have to worry about them putting it in their mouths. Instructions are pretty straight forward and all the parts were easily found and no missing pieces. Toddler has a blast even after building and makes a game of which marble makes it fastest down the bottom. Love that it fits with our other building blocks and that you can now build combinations. Love that you can build other versions and not just stick with one. Its quite big so make sure you have the table space for it.
