I haven't got this particular brand yet, but I have a cheaper, identical chrome design which isn't as nicely made as this one. Everyone who has had a go with this has been stumped for a lengthy period of time, this is an unusual puzzle as it is very obvious how to take apart, and even simpler to reassemble, but weirdly when you put it together in front of someone to show how it's done, the solution seems to vanish in front of them. It's a very, very easy solution that's very tricky to find. Great design.
