Aluminum Cylinder - AKA First Cylinder

5 

First ever puzzle and thought this would be perfect during quarantine. It was definitely worth it. Well designed and difficult. Took about 20 minutes to take apart and about twice that long to put it back together. I think the reassembly is the real puzzle. Lots of fun!

This is a lovely little puzzle. It looks good, feels great in the hands and is clearly well made. I found it pretty tricky to solve (it took me about an hour, but I'm not a fast puzzler). Strangely I found reassembly more difficult, despite having seen the inner mechanism. I'm now working my way through Strijbos' Aluminium Cross, which has so far been a slight more enjoyable experience.

I love this puzzle. Very neat and sleek design, solution is not too difficult but hard enough that you'll scratch your head at times. Definitely a level 8. Only reason I am giving it 4 stars is because reassembling it can be a challenge. One of the inner pieces can be a bit flimsy and the other pieces can get caught on it sometimes. Only with reassembly though.

Very interesting puzzle. Takes a while to solve but once you have figured out the inner workings it is still a challenge. Remember the Roman Numeral V is on there for a reason.
