This is the third ROKR Wooden Puzzle Mechanical Model Kits device we have built. All were well made with precision laser cutting of parts. and excellent instruction books. And the projector works! These are great devices for family fun – my son-in-law, granddaughter, and I are all engineers and these kits take several hours to construct. Wanted to get it a while ago and finally get it on Prime Day! Took less time than I expected (2.5 hrs). The instructions are very clear and helpful. Enjoyed it overall. Wish it came with a longer film
