Review on Wooden Roller Coaster Marble Run Puzzle - ROKR 3D Mechanical Model For Self-Crafting, Decoration, And Educational Gifting by Brandon Bullard

I seldom write reviews of products but this kit is simply amazing. It is so beautifully designed, laid out and laser cut that I wanted to share how delighted I am. There are 239 pieces in the kit. No glue or other fasteners are used because each piece is a press fit into other pieces. To make this work, very close tolerances must be held in the cutting process. The laser cuts are perfect. I'm incredibly impressed with the thought that went into this design. Like Salieri, I'm just smart enough to appreciate how brilliant this design is, but not smart enough to do it myself! I enjoyed building the kit so much that I bought another from the series. As I write this we are under quarantine from the novel Coronavirus. This is the perfect way to occupy my time at home.
