I looked at many marble runs on Amazon before deciding on the Mega marble run by Galt. The videos sold me - the runs looked smooth and the plastic looked thick and sturdy. This set did not disappoint. My 5 yr old son plays with it for hours at a time - creating new courses and sending all the marbles down over and over again. The marbles run smooth and with adequate support and the pieces stay together. We have even made runs taller than him without them crashing down. It comes with a booklet with a few sample runs, but you really don't need it. My son just builds his own and it is not at all frustrating or difficult. I hope Galt comes out with some expansion packs because we would love to add more interesting pieces to the set but all the smaller sets contain mostly the same pieces ( just less of them). This set contains 20 glass marbles, a 5/8 inch marble which can be easily found on Amazon should you need to replace them. Only issue I had with this set is that the prong things for the funnels fall off very easily and have to be placed in a certain way because of the shape of the funnel. You may need to help your little one with those. Otherwise, nothing but fun!

Bought for my 5yo for Christmas and she loves it. It is a bit easy to knock down which can be frustrating with an 18mo godzilla for a baby bro but is still lots of fun.

Got this for my 5 year old, but I think I might like it more than he does. He had a smaller Galt marble run set, which was fun, but that set didn't include some of the cooler pieces. My favorite pieces are the vortex pieces and the 2-way chute that allows you to branch marbles onto alternate runs. Honestly, I wish I had a couple more of the 2-way chutes to build even bigger, more elaborate runs with more branches... I might be developing an obsession.

Ive researched for a marble run which I thought maybe durable and easy to put together as my 3 year old daughter has always watched these stuffs via youtube. Ive read the negative comments for Galt Marble Run but still decided to purchase one since the positive review videos speaks for itself.

The packaging is great, stuffs came in protected. Also I am currently in Qatar (middle east) and still the package came really fast which is within a week to my surprise =)

To those who say its unstable/wobbly etc. You just need to learn how to put it together in balance which isn't that hard. I actually didn't use the leaflet that came with the package when my little one and I first made our first marble run structure, I just tried to put them together just like a lego and it worked well. Now she's enjoying and so does my wife and myself included =)

The marbles that came in are a bit smaller than the regular ones but im definite that regular sized marbles will fit too. I had to add a few $ for the shipping fee upon checkout which is not what is in the ad =(

still ill give it 5/5 stars as our daughter really enjoyed it well. in face she woke up early and went straight to playing again!

P.S. Wanted to add an extra set when I was trying to purchase but the shipping fee went double too. was hoping you could consolidate to lower the shipping fee perhaps? If so, will purchase another one to expand our marble run structure. Thanks!

When we first got this toy, we were a bit stressed with trying to build the model shown on the box. There were no directions inside the box, so we just kept looking at the picture. The whole marble run kept tipping and breaking while we tried to build this elaborate structure. Eventually the toy was put away and we recently just took it out again, but this time built our own creations. My kindergartner loves being able to design her own run. She has learned so many things from building with this set, like which way the pieces have to go to make the marble go through the course, how to build faster courses, etc. Now my children fight over the pieces and I'm tempted to get more pieces for more fun. Perhaps the company would be better off showing multiple pictures (some smaller structures) on the box so that children do not get discouraged when they try to build the big one.
