   We have a lot of LEGO duplos and these weeks perfectly together. If you compare piece for piece, these are slightly lighter, but other than that you would not be able to tell a difference. The mazes don’t have the best step by step instructions, but we did not find it difficult to just look at the end picture even and figure out how to build it. Great bang for your buck! My husband and I and our kids ages 4, 6, and 8 are all having fun with these!

   We got these for our 3 year old for Christmas. We already have Marble run for our 6year old and lots of Duplos, so now our 3 year old has her own”marble rollercoaster”. They work great with her existing Duplo blocks. The balls it comes with are light weight plastic balls, but regular marbles work too. All of her Duplo figures can stand and sit on the blocks and watch the roller coaster zoom by. It has been a week and a half since she got them and loves them. Plays everyday buildIng and changing the runs. They arrived quick.

   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.

   This is fun and creative activity for my kids, good quality,my kids build different things and they can play with this for an hour. But there is a thing that need to be improved is the building instructions is unclear, of course you can build on your own way so it doesn’t matter.

   My kids and I love this marble run! It can be configured in so many exciting ways and provides endless hours of STEM fun. It is a little smaller than I thought it would be but with detailed picture instructions and bright bold colored blocks, I am very pleased with this purchase.

   This was a great marble run for my kids. They work well with duplo esp their base. The instructions for the more complex run was a bit complicated but we were able to figure it out. Also the colors of the blocks were random. Overall it was really sturdy and well made. Would buy again

   I Really like this set. The chunking pieces are appropriate for the older kids and younger. They have had a lot of fun designing different ways. I Really like that duplos work with this also and they can use them to build various tracks. Easy to assemble and easy to manipulate the pieces.

   This amazing set just what I was looking for.. Great motor skill training for kids. Being home more with everything that's going on, it helps to have cute blocks that are big enough for kids. My kids use their imagination and play hours and hours... We liked these colorful and fun blocks!

   This is a really neat toy that has provided hours of enjoyment for my 11 and 6 year old son. The pieces fit very well together, it is sturdy and stands up well even on carpet. There are couple of ways to build these runs, and never gets boring. We highly recommended for kids and even adults.

   My kids love building and this set has been perfect to curb boredom while they are forced to play inside while it's so hot outside. My 4 year old in particular loves to run the marbles through his creation and my 7 year old joins right in on building the marble track. Would definitely recommend!
