REMOKINGMarble Run Building Blocks, 2 in 1 Compatible Blocks Models with 8 Marble Balls，Educational Race Track Building Block Set, Great Gifts for Kids 3 Years and up（259Pcs）

Wonderful product. Pieces all fit tightly together. Beautiful colors, the "marbles" - which are plastic hemispheres that you put together yourself, seen to be weighted well and were easy to assemble... and they move smoothly through the track. My only complaint is that the instruction colors were quite off for the brown and red peices- in the instructions the red peices looked like a tan-ish orange, and the brown looked black in the instructions. It made the instructions a little confusing at first but I was able to figure it out in the end. One slight mishap - the manufacturer sent me one too many pieces in one shade of blue - and one too few pieces in another shade of blue. It made assembly a little confusing the first time because I was being very careful to follow the instructions to the letter and when it looked like I was missing a piece I went back and partially disassembled the structure to see where I went wrong- but once I realized that the extra piece and the missing piece were the same size I just put the extra piece where the missing piece should have gone... so it all still worked. I won't need to be so careful about the instructions in the future- I just wanted to do it exact the first time to make sure no pieces were missing. Overall, this product is fantastic and I definitely recommend it. :)

I bought this set of Hubelino-style blocks mainly because I blanched at the cost of real Hubelino (which is about $200) on Amazon. The plastic bits fit together well and are of good quality, although perhaps not quite as good as Duplo. The manual is not as clear as Lego manuals, but it does the job. The marbles run through the kugelbahn okay, but they are quite light and not much momentum to them, any slight imbalance in the course and they stall. I might get glass marbles to hopefully overcome that problem.The main drawback is that although its a 259-piece set, most of the bits are quite small, so the overall course is quite short. You will pay around double for a Hubelino set with the same amount of pieces, but the pieces are bigger and add up to a bigger course. As well, you dont have any of the above problems and I suspect that your kids will have significantly more fun with it.Its not cheap for what it is, either. The Chinese grocer near my house sells smaller sets of Chinese hubelino, they start from $9. Price wise, you're paying significantly above the nose for this at $100 AUD.

I really like the set! It’s Lego duplo compatible and is so much cheaper! Great value and a lot of fun!

This was a birthday gift and my grandson loves it!It works like it’s supposed to. I just ordered a dinosaur one for my house which I’m very disappointed in. The marbles fly off the track due to ball accelerators.

My husband built it for my 20 mo old son and it was not sturdy. Kept collapsing with a little bit of pressure.. for example, the balls would get stuck and not slide all the way to the end. It'll get stuck in a "tunnel like" part and the pieces would fall off if you tried to lightly get the balls to roll down as they're supposed to. My son got so frustrated, he broke it into pieces after a few hours because it didn't work how we expected. In my opinion, it was a waste of money, but it does have a manual with different builds so try the different builds out if you want.
