Review on 🧩 ROKR Wooden Marble Puzzles: Mind-Testing Fun for Adults by Michael Cormier

I've built several of these ROKRs and it was the most fun. The guide is great, but there have always been instances where I had to disassemble multiple modules to get them right. After the basic build I spent hours adjusting things and modifying the rails so the metal balls would actually flow or stay on the rail. I needed super glue to hold some of the joints together. Highly recommended for those with building and mechanics knowledge. Others get frustrated after a long build, only to find that the finished product needs a little tweaking.
