   These pieces work perfectly with Lego Duplo blocks. My 3-year-old loves working with us to assemble the maze, and he was enthralled by watching the ball run through it. The ball is small enough to be a choking hazard, and he did put it in his mouth once, so, if you have a younger child, I'd only let them have the balls with supervision.

   Very entertaining and educational toy for kids of all ages. I bought it for my 3 year old who likes to play with lego duplo, she enjoys mixing and building it with her own duplo sets cause it’s completely compatible. I would say the quality is as good as duplo. My older kids are building all kinds of different marble runs and it’s so much fun. My kiddos not really following the instructions, they’re preferring to build according to their imagination.

   Great set of blocks that are compatible with Duplo. It is a great addition to the many legos we own because these have the slides and additional unique pieces that our Duplo set did not come with. Blocks are sturdy and stick well together. I like that you can also build the balls and mix and match the ball colors. Comes in giftable packaging.

   I have a two year old that can spend hours building different structures so this is perfect for her! We love the product but found we had one missing piece which I foresee causing some drama in the future, but I was able to contact the seller who graciously sent over a new set. Wonderful and quick response to the seller! Good experience overall.

   My three year old granddaughter loves this set. Although the instructions are difficult to decipher and too small for my old eyes, I would order it again because of the customer service department. They were quick in responding and very helpful with my questions. We were able to add her other block set because it was compatible with her new one.

   My 2 years old toddler loves mega blocks. So I bought marble run blocks. It is super durable and colorful. Quality is very well enough and perfect for all ages. More challenging than mega blocks and more bigger than others. And I am playing with it together with my baby. The instructions are easy to follow. And it is stimulating the brain to have to build.

   This set is great fun! Even my two year old granddaughter, was able to piece the tracks together. We have lots of fun playing together. I was able to take some of the extra pieces and make a trough to hold the marbles. Having two green boards means two children can build separately at the same time. My picture is made from the 97 pieces that came in the set.

   This marble run game is very easy to build and includes more than enough pieces to build almost anything. I put together one of the included designs and the kids love it. I like that the pieces are a little bit bigger so small kids can assemble and disassemble with ease. The pieces are compatible with other name brand blocks as well. We should have lots of fun building with this.

   It’s really a fun game that can keep little ones entertained for hours. More importantly, the customer service is very responsive and beyond excellent. We had a small issue with the base plates and contacted the seller. We got the replacement very quickly and a nice follow up email to make sure that everything works out fine. Good product and excellent service. Highly recommended!

   This block set keeps my daughter occupied for hours sometimes. She has big blocks but never really played with them, and one day we were at a friend's and my daughter played with her friends set of small blocks and wanted to take them home with her. I was on a mission to find her similar sized blocks and I stumbled upon these. They fit together well and are durable. Absolutely recommended!
