This was my first rokr project. Loved putting it together and love the final result. Great quality product with clear instructions. Takes a little patience to complete so I did it in stages. Will be definitely purchasing another one.

Amazing! Here in Argentina we unfortunately do not get these things

Easy assembly with smooth cuts and detailed instructions. Will order another soon

Great design and smooth cut outs, lot of fun to build. I added a few braces, Motor with a Speed controller, I also added a Paper Clip bent in a U shape Drilled two small hole in the top ladder Bent the Open ends of the U clip in inserted in the holes. Kept bending the Bottom of the U clip until it drops between the first and second Ball. This allows only one ball at a time to go up the ladder. I can run the motor at a speed and never drops a ball. Even when a ball get caught in the gear the next ball clears it and my clip still only adds one ball to the ladder. My belt just slips on my plastic pully. Love this version I even added Led lights. Could not send Picture.

Not a bad kit. Good laser cuts. Instructions adequate. Put together, got one part reversed and left out one but found both as the assembly progressed. Worked the first time. Drops a ball occasionally but probably due to not being screwed down to a solid base. Overall a fun little project.

Got this for Christmas. I do RC modeling and thus have experience with a lot of laser cut items and I will say that the quality of the laser cutting on this was outstanding. The engineering behind the kit was quite good. I see a couple people mention poor quality instructions and I am not sure what they didn’t understand. They had detail views that made important details apparent and the rest of the build illustrations were well done. I highly recommend this kit and I look forward to checking out others.
