Very excited to receive my order I couldn't wait to start building after carefully looking over everything I started to build the marble run it took me about three days to compleat only doing a little each day after I completed it I tryed it out but found I had issues with the lift but after some minor adjustments all was running very well I'm very pleased with the purchase and well worth the money I hope the team at Rokr make more of these marble runs so I can collect them thank you Rokr on an amazing product cheers

These marble runs are fun to build. The model is well designed and works well. It took me 5 hours to build. I have the two together and hoping that there will be two more in the future.
