[This review was collected as part of a promotion.] I bought this for my great nephew's birthday and he loves it.  He watched videos where a person built marble runs so he was very happy when we could build his own.  Great value and quality construction.

[This review was collected as part of a promotion.] It's sturdy. It's easy to put together. This is the best marble run  I have ever purchased. Other ones  are thin and are complicated for younger children to play with. This has thickness to it and is sturdy. Plus I have been looking for Legos that are easy to put together for my 2.5 year old. I find this is not too much for him to connect pieces together. Love it. I recommend. Great for cognitive development as well. Does not frustrate  younger children.

[This review was collected as part of a promotion.] Enjoyed playing this with 3 year old grandson. Just make sure we are past the stage of putting items in mouth. Had lots of fun experimenting with the tracks %26 seeing who's ball could go the fastest.

Fun for grandson! Makes you think!

[This review was collected as part of a promotion.] This is such a fun toy that really gets the kids to explore and understand physics. I bought it for my 18 month old because she loves cause and effects. I only let her play with the marbles under my supervision because they're a choking hazard. We both really enjoy this toy!

SO FUN!

Much better than the other plastic ones, this one is much easier for kids to put together and it's super cute!!

[This review was collected as part of a promotion.] good toy...our kids love it..

marble run

[This review was collected as part of a promotion.] It's fun but a little bit challenging.

Fun but challenging

[This review was collected as part of a promotion.] It's great for kids to put pieces together on their own and for them to create what they want too.

[This review was collected as part of a promotion.] The directions are awful. The pictures are small and its hard to make out what the part is and how they want it. I wish there was a video assembly. The one design i managed to do doesnt really work. There are no extra pieces so if something gets lost you are screwed. 

I love the item of this and that it uses duplo like legos so i can add in duplos i already own for support or height. But man the directions are awful.

The directions are terrible

[This review was collected as part of a promotion.] Y'all take this as your warning. Your toddler won't be flipping the table.. you will be. These pieces do not fit together well and the slightest bump knocks the whole thing over. 

176 pcs and it only shows SIX STEPS. You got it.. SIX! 

It's so small I had to take a clear photo and ZOOM in on it to attempt to build. The photos are not clear regardless. 

Save yourself. Go for better quality. These were on sale, and I now realize they were marked up significantly for the quality.

Don't be fooled by the “sale price”.
