Solved this the day after I got it. I got the answer just by thinking about how it must work, then simple manipulation. It's well made, looks good and worth the money to me, even though it's pretty much a one trick pony. I'm glad I got it and will see how my friends get on with it. I also have the 'Padlock' which I found much harder and way more entertaining - that took me a week to figure out.

This puzzle is even better if you have some knowledge of machining and the constraints of assemblies. SPOILERS. OTOH, I was a bit unhappy with the lead-in angles on the bolt threads; the nuts do not rotate on the threads as smoothly as on a straight bolt, so this causes some frustration in figuring out the alignments. Yet, maybe this was intentional, to increase the required dexterity

It was fun. But definitely easier than level 6. I would give it a level 3 difficulty. Overall it is good value for money.
