COUOMOXA 110 Pcs Marble Run Set, STEM Building Blocks Toy | Marble Maze Race Track Construction Kit for Kids Ages 3-5 4-8 8-12, Educational Birthday Gift with Glass Marbles

I loved the idea of this marble run. We have purchased several other Duplo compatible marble run sets over the years. When we first bought one they were really only just a couple of options and the options didn’t really come with a lot of fancy pieces or anything. Now you can get all kinds of cool gadgets for it. Anything from multiple different kinds of ramps to animal shaped pieces and now elevators even. It keeps getting better and better. FYI the xylophone piece Pictured is from a company named “grabhappy”. My kids absolutely love it, with all of the variety we have now and all the different pieces they can literally spend hours building these runs and I love it. They get to use their imaginations and creativity and problem-solving skills and they get to do it in a way that is fun for them and rewarding when they finally get done with their creations and they can drop the marbles down. There is in my opinion only just one notable drawback to this product which have me taking away one star.. This set uses the same plastic marbles that every other set uses I believe. They are not good. They come disassembled in halves, you must smash them together yourself.. which is ok, but they break back in half and the prongs break on them and they cannot be used anymore. Also important to note is that is very difficult to find replacements for this. I have contacted the manufacturer of every single one of these sets I bought and here is how each responded: Temi toys never responded. Wx hobby, a company that makes a really neat but unstable electric elevator lift for these sets responded Simply by letting me know these marbles should be fine. I happen to disagree. “couomoxa” (the maker of this set) said they could not replace the marbles because they do not have the ability to do that, but offered to send me a returned set with marbles included free of charge because of the hassle of the broken marbles. I thought that was very nice and because of the amazing customer service response I’ve added back the star. Another company named klobroz does sell a replacement pack! But it also includes other pieces I don’t need. It was $10 and has 6 marbles and some run pieces too. Not bad.. but also they had very low stock and I’m not sure if they will replenish the stock or not. Time will tell. I went ahead and bought two packs. It had been two years since I bought their marble run set, they did not offer to replace the marbles for free but did kindly offer to give me a $5 refund credit for the trouble to apply towards the purchase of their replacement pack. Good company response. A company named “grabhappy” told me they cannot replace the marbles and did not know where I could find the exact marble, but they did offer to compensate me in the case of broken marbles. It is important to note that I just bought that set Within the last few months and I am not sure if I contacted them in a couple years after the marbles break whether or not they will go ahead and compensate me or if they would just say sorry it has been too long. Either way their response made me feel like they would stand by their product and I appreciated that so I am very grateful. If you are going to buy this set then know that you may not be able to replace the marbles so keep good track of those as well. Klobroz does sell a replacement set but being it’s low stock right now and no other replacement set exists, it may not be for sale forever. Although the drawback of broken marbles had me take away a star, the great customer service had me add the star back and I cannot recommend this set from this company enough. Thanks My kids spent hours on this, building and using their creative imaginations and keeping themselves busy and they love doing it. It fits really well with Duplo‘s so if you have a good stock of Duplos than this and other of these sets provide really cool creative opportunities to expand on your collection and have a lot of fun.

Great fun! I thought i was missing a part but you have to dig through all of them to find it.

This is a really nice marble run set. We bought it for our 3 year old grandson. The blocks are large and brightly colored, just like the name brand ones you buy for small kids. We liked the fact that you can put together 6 different configurations. That’s great as your kid won’t get bored. The set arrived on time and was not damaged. No missing parts. We decided to put it together right away so our grandson could begin playing with it. The directions are BAD and assembly is a chore. The problem is that the directions require you to use a green rectangle, for example, but the set doesn’t have a green one. You might get a blue or pink one in your box. So you try to put it together but think you’re missing the right piece. Then you figure out that the colors in the directions may not be the color included in your box. Hope that makes sense. We selected one of the “easy” designs and it took us almost one hour to construct it. Our grandson was bored out of his mind, too you g to help, and disappointed it took so long. Oh, and there are no marbles. At least not real glass marbles. Which is rather strange since it’s a marble run toy. You get 4 plastic balls that are two pieces that snap together. So it’s a plastic ball that is much larger than a regular marble. Once you get it put together, it’s fun. But you dread having to take it apart in order to fit it back in the box. The thought of starting a new run is somewhat painful. Hoping our grandson will create his own towers or whatever. With “marbles” or not.

I will buy more of this product. I like the uniformity. The parts click into place as expected. The challenging part is assembling a sturdy structure. This takes a degree of forethought that will likely stump the toddlers. My seven year old enjoys it, and though my 2 year old isn't an experienced builder, he enjoys rolling the balls down and observing. The product successfully merges the traditional building blocks with the fun puzzle skill of a marble run.

We have TONS of lego duplo. We have no other marble runs to compare to. These pieces fit perfectly with our lego duplo which meant that we were able to expand this set with pieces we have from our lego sets(like a propeller for the ball to hit or building a tunnel for the balls to pass through, etc). The criticisms people have left in lower star reviews are not that big of a deal. Yes the balls snap together and are somewhat lightly weighted. Yes, the instructions are a bit confusing. Yes, the pieces are weighted slightly differently than lego brand pieces. Yes, the base plate for this set was a little warped(we ended up using our own lego brand plate to build on). But ultimately it works well and is easily expandable.

The step-by-step instructions are very small, making it difficult to make out the exact types of blocks needed for each step. All of the colors are wrong, so a greater level of abstract thinking is needed to achieve each step. Structural integrity of each design is very weak, so you'll want to use your engineering skills to shore up support using additional blocks. Overall they seem to fit together well, and seem to be compatible with other brands. The base plate has some small nodules leftover from the extrusion process. You'll want to file these down so blocks fit flush against the base. Given these difficulties, the set is definitely overpriced. I knew that going in (thanks to other reviewers) because I really wanted the see-saw, which I haven't seen in any other set. Bottom line: With the above caveats, the kids will get used to it, have fun, and learn valuable lessons. Chief among them is that you don't always have complete or reliable instructions, and you will need to rely on your wits to solve problems, but the rewards are within reach.

We love building with Lego and Mega Blocks so I was very excited when I saw this! We already have a lot of Mega Blocks so we love that this set is compatible with them. I've been wanting to get a marble maze for my kids but was always hesitant because marbles are so little and obvious choking hazards. The balls that came with this set are the perfect size. I also appreciate that there are only 4 because it's a much more manageable amount. The instructions for suggested builds are great to have and easy to follow. The parts seem to be made just as well as the Mega Block brand, nice and durable. We have absolutely gotten our money's worth and have only had them for a few days.

This marble maze is the biggest hit of my 2 year olds birthday - me, my teenager, spouse, and the actual birthday kid are all huge fans. The instructions aren't Lego quality, but the pieces themselves are compatible with Duplo and 2 large bins were used to make this giant behemoth, which uses every piece of the maze. You cannot build with every piece of the maze without additional bricks. I also am buying more base plates. Overall, great for a Lego/Duplo lover to start a maze collection with.

I purchased this product to go with our existing Duplo blocks and the are pretty much perfectly compatible. I couldn't tell the difference between Duplo or these bricks. My son (4yrs) thoroughly enjoys building with the tracks and we hope to purchase an additional set when back in stock.

Good product - but not enough marbles - and cant see where to buy more!?

The pieces do not click as good as duplo so when a kid touches it, it falls apart easily. If you want this to last a few generations or few kids to play, it is better to invest in original brand Hubelino. It is more sturdy and even more fun for kids to play. It was a good idea to try if our little one likes the concept of it.

A mi niño de 3 años le encantó. Armamos juntos los modelos y como los bloques y partes son grandecitas, me puede ayudar muy bien.
