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

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!

I bought as a gift from my brother to my son. He loves it, he will put the balls on the top and watch them go down for hours, he helps to put it apart and put it together. We added other Lego pieces for structural issues, I felt like it is not enough pieces to make it tall and sturdy. We rearranged and did our own way! It is very fun, it has been his favorite toy for over a month now.

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.

Good item

The bottom piece as received was not large enough to follow any of the provided directions. We had to be creative and make our own, but My 3 year old was frustrated that it didn't look like any of the pictures.The pieces are easy for him to take apart and put together, so this is higher quality than the Lego marble run we purchased from Shein.Overall, we will be keeping this marble run because we can get creative with it and just throw away the instructions. However, I would not purchase from this company again.

Bello

This marble run is awesome!!!! it comes with 4 balls to use that are bigger than marble size. Regular marbles also work nicely with this set & play nicely on the xylophone. It comes with more than enough pieces, FULL INSTRUCTIONS of how to build a number of different designs. TAKE MY WORD YOU WILL NOT REGRET BUYING THIS! I am a content maker on YouTube & this fit the bill 200% Love it!

Hard to put together and the parts don’t fit right once they are together. Very flimsy. Low quality not worth the price. Also was missing a crucial piece. We waited til past the window of return to put it together so we are out of luck .
