BATTOP Marble Run for Kids Ages 4-8, 167 PCS Classic Big Size Blocks Set, Crazy Marble Run Building Blocks with 4 Balls Race Track, STEM Toys Bricks Set Christmas Toys for Boys & Girls

This toy is excellent for encouraging creativity and fine motor skills. The pieces are designed to be easily snapped together and taken apart by little hands, which is a big plus. The thoughtful design makes building a breeze, and it's clear the creators focused on making a toy that is both educational and very fun for kids.

My little guy loves it!

The media could not be loaded. Overall my 3 year old was really excited when he opened this as a present and had a lot of fun with it. I put 4 stars because it was kinda complicated… my husband was getting frustrated with it because he’d be trying to build it and it would break on him. We’ve had this for over a year now and we’ve only built the track (like we had it in the video) once because it’s super complicated and the directions/pictures aren’t great and are hard to follow. However, my three year old will just put the pieces together and create his own little track flat on the base. He likes playing with them a year later but for those reasons I only put 4 stars. The price is great though! They are compatible with DUPLO but you can definitely tell there is a quality difference.

I bought this for my son's 5th birthday. He has built it almost every day for the last 3 weeks. It comes with directions for 2 ways to build. I felt the directions were clear. My son needed a little help with the directions at first, but can build independently now. There is a flaw: the marbles don't consistently make it all the way through the courses you build with the directions (hence the slightly lower rating on Easy to Assemble). Some times they do, sometimes not. That bothers me and my older kids (ages 8 and 10), but the 5 year old doesn't seem to care! I disagree with other reviewers who felt the pieces didn't fit together tightly. They are sturdy and fully compatible with duplos, and it really adds to the fun to combine them. I personally enjoy "tinkering" with the set and building new runs, as does the 5 year old. Building from the directions a few times first helps to understand how the different pieces work. If your child is a perfectionist or doesn't enjoy "tinkering" and "trial & error", they may find this set (or any marble run) frustrating. One thing I like about this duplo-based set over other marble run sets, is that it only takes a few of the pieces to easily build something that's fun to put marbles down. Plus, my kids are such frequent Lego users that there isn't much of a learning curve to making the set work. Overall, I'm glad we bought it!

Colors beautiful. Really good building bricks for kids.All compatible with all Major brands.But, color kind of waxy and the marble tracks constantly unconnect and the pieces just constantly fall off. But if you are ok with your buildings accidentally being broken. Then this is a great set for your kids.

Grandson love's it... 3 years old and he put it together.

My child loved this!

I bought this toy for my 2 1/2 year old disabled patient. I tried all 3 versions of putting it together, but it’s very flimsy and the balls hardly make it down all the way. Not to mention the instruction book that came with it. It’s very hard to see where the pieces need to go, pretty frustrating. Make sure you have a magnifying glass. All in all not very happy with it, and not getting much use out of it. I don’t have the box anymore, so we can’t return it. I gave it a two star, because it does look pretty sitting there.
