Safe Puzzle - Very Hard Puzzle

It is a beautiful puzzle and very nicely made. My 9yo spent his hard earned money on this and solved it within 15 minutes of opening it. He doesn't feel disappointed though. He got the coin back into the safe in less than 10 minutes.
I would give it 3 stars, but he insists on 4.

This puzzle was very well-crafted and provided a satisfying challenge. It took me roughly 2 hours to solve and put the coin back in place. What truly impressed me were the cleverly designed "traps" incorporated throughout the puzzle. These unexpected elements added to the difficulty and kept the solving process engaging.

Was a fun puzzle, but the coin got stuck going from the first layer to the second layer, so after around 15 minutes of shaking it I had to drill a tiny hole through it to push it through. It also might just have been luck but the time that it said it would take to solve was drastically off. I'd say that it should be an hour and a half instead of 5 hours.

Very good spinning mechanic puzzle, I enjoyed solving it. After solving I'm not sure how to reset it, I don't know if i need to open it or not but just ended up doing the puzzle backwards well tried. I don't want it to be easy for the next person so if theirs a way do let me know.
