This is a trickly little puzzle. It takes a while solve, but then still takes a while to figure out the pattern for assembling and disassembling. This being said, the shining coating is not very durable and comes off rapidly when fiddling with it. The puzzle itself deserves 5/5, however because of build quality issues it gets a 4.
