That is an extremely satisfying puzzle. The way the pieces are tungling together is so exciting! It reminds me of two of my favorite Hanayama puzzles: Donuts and Marble. It looks like Donuts, but acts like Marble. However Wavelinks is a cut above in quality, it is more interesting, it feels much more solid. Anyway I like having them all. Displaying Donuts as a little brother togather with solid and bigger Wavelinks is pretty interesting. Especially considering that they have different solutions and different mechanics. And you can assemble Wavelinks in two ways: a black donut and a white donut or two black and white donuts )

The skill required to hold all four pieces is a great challenge.

Exquisite puzzle with one of the most satisfying solutions around … and if you’re kinda fidgety like me, it has endless value after solving as it twirls and swirls in the band seamlessly

Exactly as advertised, a very refreshing experience. Everyone is enjoying my collection of puzzles
