What a fun activity for your kids. I bought this for my son and daughter to Play instead of having endless of screen time. They love it snd have been playing with it for hours! It’s great quality plastic and had so many pieces for variety! Great colors and size

There are not enough stars for this great marble run set! I was a little worried about purchasing an off-brand Lego/Duplo set as we had tried a non-Lego block set in the past and they were cheap plastic with sharp edges that either didn't stay/fit together or were impossible to pull apart. This set though was absolutely perfect! You couldn't even tell the difference between these and the official Duplo blocks! They look and feel exactly the same and fit together perfectly. They also have lots of fun pieces with tall towers and all kinds of curves, slides, and marble drops. If your child loves playing and building with Lego/Duplo, then these are an absolute must have! :-)

Hard to put together

Excellent children’s building set! My child enthusiastically assembled various models, which helped develop his imagination and fine motor skills. The quality of the pieces is outstanding—they’re durable, safe, and easily connect together. The set brought a lot of joy and proved to be a great way to spend quality time. Highly recommended!

I’m leaving this review because I’m very salty about my customer service experience. So my child ripped up the instructions after getting frustrated with the flimsiness of a model he was trying to construct. I reached out to the customer service for another copy of the PDF which I did plan to laminate just in case for the next time but instead I received this whole spiel about VIP service after scanning some QR code that was provided in the box originally and in all that time they could’ve just attached the PDF. Now I have to throw the whole set away because I don’t have the original card they were talking about because it could’ve got ripped up with the rest of it. I just don’t understand why not just offered to sell it to me for five bucks or something putting us through extra hurdles for some instructions is ridiculous to me. The kind of service they’re offering is more relevant to electronics or something like that not blocks. I don’t need a warranty on building blocks. I just need replacement instructions simple courtesy any manufacturer would provide from what I’ve observed.

My son has really started to enjoy duplos while this also offers the marble run which keeps him excited. He has played with this for hours, My son is almost 3 years old so I'd say good Age range, just always watch your children while playing with small pieces. This marble run has a variety of pieces, many different colors and animals. I'd definitely say I got my value for money spent.

I bought this building blocks for a birthday gift. My nephew loves it. It's durable, colorful, many shapes. He can play for hours with it, he loves dinosaurs. Happy with purchaes.

It looks like it is an interactive toy for our children, it is a gift for my niece, and although we will not be able to assemble it together, I know that she will enjoy it, it is very well packaged, I do not disarm it but if I opened it to see if quality and it is pleased, I hope it is to your liking, because I like it very much, the instructions are clear and logically it has to always be under the supervision of an adult.
