"After building several other smaller scale products with 4 year old grandson, I thought I would attempt something more challenging to keep busy during the pandemic. I was not disappointed. It was challenging but the easy to follow directions made it a fun adventure. I would agree with another reviewer the dark background made it extremely hard to see some of the detail in the booklet. I did however use the online instruction manual about half ways though which made it a lot easier to see the color detail. I did enjoy and would recommend to friend."
