Marble Run Building Blocks, 145 PCS Classic Big Blocks STEM Toy Bricks Set Kids Race Track Compatible with All Major Brands Bulk Bricks Set for Boys Girls Toddler Age 3,4,5,6,7,8+

The media could not be loaded. 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 two notable drawbacks to this product which have me taking away one star..1. The baseplates that come with these sets are not very sturdy, sometimes warped, and do not hold the set together. To solve this issue I made my own DUPLO table using a Melissa and dough activity table and some large DUPLO baseplates I got from amazon (that are no longer sold unfortunately) that I have cut to shape and caulked in place. It works really well and I can flip the top over to be a regular non lego top when needed. When using this instead of the provided baseplates the set is just stable and fine when built correctly.2. 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.One good company named “couomoxa” 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.klobroz (the maker of this set) 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.Despite the drawbacks, because of the amazing customer service response I am going to give this five stars and I cannot recommend it enough 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.

Grandson loved it

Kids love it

I purchased this set as a gift for my three year old grandson who adores marble runs. We decided to put the run together prior to wrapping the gift so that he could play with it right away. The blocks and base pieces are well constructed and easy for little hands to hold on to. The colors are great and very appealing for kids. Now, I am very good at spacial concepts so assembly should have been easy, however the suggested construction layout phicturs were small and difficult to decipher. This resulted in trial and error in some areas but I managed to work my way through it. The "marbles" are a nice size plastic ball that comes in two pieces - not real easy to put together. Would be nice if they came in one piece. The base comes in two equal size pieces that only connect together when you span blocks over them This made picking the piece up to move it a bit precarious. I ended up attaching the base plates to a piece of foam core board with double sided tape so that we could move the assembled toy into a sizable box for careful wrapping. Over all, this is a fun and educational toy for kids. I think that kids under six years old will need adult help to build a run of any size, but they are able to make small hand held versions. My only reason for not giving this toy five stars in that the base plates do not connect solidly enough to pick the large run up without danger of it coming apart and that the plastic balls come in two pieces. I would buy this again.

Was perfect for my granddaughter easily built and many different things to build.

This Marble Run building block set is such a fun and creative toy! I love that it pairs perfectly with brand-name Legos, making it easy for my kids to combine it with their other sets.The cute design and bright colors are so appealing, and the pieces are the perfect size for little hands. The playability is endless—my kids (ages 3 and 5) absolutely love building unique tracks and watching the marbles race through them. The sturdiness of the blocks means their creations stay together, even with all the excitement!This is a great Marble Run concept for young builders. If your kids enjoy Legos and love to create, this set is a must-have. Highly recommend it!

I gave this as a gift for my grandson who was turning 3. He was delighted and most excited about the dinosaur figures. He made sure to show me how the baby dino can sit on the mommy dino. His older brothers have Legos now he can play with building blocks just like his brothers with his very own set. This set is colorful and delightful to a young child. I had looked at other sets but the small pieces worried me as a choking hazard but this set does not have pieces small enough to swallow which is why I chose it.

This set works perfectly with Duplo's. The balls are a little cheap and come in two halves that need to be assembled for some mysterious reason, but everything else is great. This set has been played with every day for months. Honestly, the biggest reason why I bought two more sets was that I had so much fun setting it up that I wanted more for me to play with (It didn't hurt that there was a sale on though). Of course, my two year old loves it and has been building tracks first thing every day. He can't eat breakfast without having it at the table. But do my husband and I love it more?... Probably 😉😁The only thing I would note is that one set is probably not enough. It's also really nice to have Duplo's around already to get more height and therefore speed. But these are indistinguishable from Legos, aside from the additional shapes that are useful for building marble tracks.I love these so much, I'm still tempted to buy more and set up huge Rube Goldberg machines... But I'll have to make do with the 3 sets we have for now.
