Hard to solve puzzle unless you know how to pick cheap bicycle locks. Can jam and be difficult to realign. However it is a toy, just a puzzle, so no one is complaining. Took me 2 minutes to open it. The U bolt puzzle is much better.......... I could not figure it out until I went to YouTube.

Bought a few of these puzzles for when I have downtime at work, I solved nutcase in 90 minutes which was dissapointing as I was hoping it would take me a few days to solve. My co-workers were very excited to try to solving the nutcase puzzle. precision and patience are the key to the puzzle
