Review Content Great Learning Toy! I purchased this for my sons 10th birthday. He enjoys construction and putting stuff together. This marble run was perfect for him! Although it took a while to put together, he enjoyed the process. It was also a good bonding opportunity for him and his stepdad. Now that the run is completed, my son likes to invite friends over and race marbles down the track. My favorite part is that he was able to learn about following directions, precision, and a bit of engineering while having fun! Great fun for my boys! This was a great long lasting toy that took my two boys working together quite a while to set up - really challenged their problem solving skills! They had so much fun seeing what they were able to build and then be able to run it. I would definitely recommend this marble run as a great activity for kids this winter. easy fast and on time Easy to order What a great thing! Our kids grew up with Marble Works. This is Marble Works, the next generation. We had nothing but fun with it! Best Toy of Year for a reason Gave the gift to my nephews. It was best gift according to all the kids. They were more focused on it then any other gifts and caused some frustrations as other kids didnt get it for christmas. Love, Love, LOVE! My 6 and 4 year olds are going to be entertained for hours! I bought this early for Christmas and was not disapointed. Cant wait to see their faces Christmas morning!
