Quadrilla Marble Railway, Twist and Rail

My 4 yr. old son loves this toy! He understands the building concepts and likes to change the configurations (with my help). The only caution I have regards the marbles. I have caught my son putting a marble in his mouth before. So I only give him about 5 or 6 marbles at a time and don't let him play with the marble run unsupervised. When he's done playing, we put the marbles away. When he's older, I don't think this will be an issue. And--I think he'll still enjoy playing with this.

I have played with Quadrilla at toy fairs and found that, while it's aesthetically appealing (forms, colors, etc.), it actually has limited appeal in the long run -- there are only so many things you can do with it. I vastly prefer Cuboro and Chaos Tower for complexity, variability and beauty.

I am very disapointed!! one wrong move and it comes crashing down!! I must not have the secret that everyone else has.. but my children are very upset when it falls.. as am I because I have to spend time building it up again. I'm sending ours back! PLUS the marble stops in the middle of the track and we have to push it which one hard push and there it comes down yet again!! what am I doing wrong??

My son received this for Christmas when he was four. We looked at the plastic marble mazes, but decided to go with the Quadrilla because it seemed more durable. It has been one of the best toys we've ever purchased. I can honestly say my children play with it every day, and now that my son is older (almost 6), he's constructing his own marble runs...quite elaborate. He and his younger brother will spend hours trying different combinations. This toy is in our living room, and when guests come over, they think it's a sculpture. I'm considering buying more pieces for his sixth birthday. This toy is well worth its cost.

Trains, cars, movies... Nothing compares to this toy! My 3-year old son loves this toy so much that he watches the instructional video over and over. A great toy, and the peices are easy to fit together. It's the type of toy that will grow with your child.
