Really good quality marble run. Only suggestion would be to make the manual a little bigger because the print is so small it needed an adult to help put it together.

My 3 and 5 year old saw this and were immediately excited to take it out and play with it. It is easy enough for them to do almost all construction with some adult supervision and help. I will warn you there are a lot of pieces (as advertised on the packaging) but I like that it gives you freedom to construct it however you choose with some guided diagrams. I forgot to take a pic of it constructed but it is well worth the investment for kids that love to build.

My kids absolutely love this marble run. Yes, putting together took a little time but the hours of fun we got are beyond worthwhile. This is good for a wide variety of ages. My 4 year old enjoyed it as much as my almost 9 with all the others in between.
