The marbles are normal size which is a plus. Some of the marble runs you need a special small size. The pieces are easy to put together and you get enough to actually make something fun. It is a little beyond my two year old, but she is able to put the pieces together and can build towers, even if she can't follow the directions or come up with a marble run that will work. Once it is together she loves to put the marbles in and watch the go through the maze. The pieces fit together well enough that she doesn't break it every time she puts marbles in. The only thing I wish was that the bottom pieces where the marbles come out had a bigger well, because if you put a handful of marbles in at one time, there isn't enough room for them all at the bottom. Also if you do put more than a couple marbles, it can get loud, but that's part of the fun I guess.

This Marble Run is great!! Got it for my 6 yr old son and he loves it! The set comes with an instruction manual that offers 4 different suggested set up options. We tried the first one so far. It took a little while to set it up but it wasn’t difficult and once done it worked!!! The plastic pieces are durable and snap together nicely and there were tons of marbles included! My son had a lot of fun and it was great that there was no technology involved !!

Enough pieces for lots of different designs. Big hit with the kids. My 5 year old twins needed a lot of help. Basically I put it together but we used all the pieces on a huge design. I think they'll be able to do simpler designs once they grasp the concept

It arrived on time it’s a Christmas gift, but I’m sure my son will love it 😊

My grandson loves to see how many ways he can build the Marble Run into.

My 5 year old special needs grandson needs sensory toys and he loves this.

My 6 year old loves it and now wants more sets. Hoping it's compatible with the marble genius pieces. He's getting a lesson in engineering and learning to stabilize his builds and making sure they don't tip as he's assembling them.

Huge set for the money. I’ve given this as a birthday gift to kids turning 5-7. Always a hit.

This set is awesome for my 5 year old. He loves it! It’s proabaly the only toy that keeps him busy for more then 5 minutes 😀

Great for the money! The plastic ended up being more sturdy than I expected!
