Great gadget. Very satisfying to solve!
I got this puzzle today and it's a great fidget toy! Feels solid. The 2 middle nuts rotate smoothly and can be spun with one thumb. Enjoyed the "Nutcases" challenge to swap the nuts over First of these puzzles I have bought so will look at others in the future.

mind melting for such a simplistic design, excellent!
All I can say is it's witchcraft, solved and replaced took me about 4 1/2 hours, I got it apart after 3 didn't know how lol, took another hour and a half to figure it out and get it back to the start position. I know how to do it now in about 90 seconds, do I understand how it works you may ask? ......no 😂 its just 4 pieces! The loops are identical as are the two halves of the centre section the designer is in my opinion some kind of wizard and it's been enchanted haha, well worth the money, very clever and a wonderful brain teaser.

A fun puzzle, but the manufacturing tolerances are frustrating
The puzzle concept is great; I tried a few different approaches and found myself stuck, picking it up and putting it down several times over the course of a few days. Today I finally solved it. It was an approach I'd already tried, but I found that just expecting it to effectively "fall apart" when I got the correct solution was not going to happen; it required a little bit of encouragement to separate the first piece (a bit more of a firm push), and the same putting it back together. Aside from that, I very much enjoyed solving it

Not easy to solve
Took my dad a number of hours, over several days to solve, and then put back together. Has passed it back to me to have a go, and I kind of solved it after about three hours (over several days). However, I can't really say I've solved it because it just fell apart in my hands. Now I have to work out how to get it back together. It's not just a question of getting it apart. You have to understand how it came apart. Otherwise you haven't really solved the puzzle. It's well made and solid. I didn't see any sign of the finish coming off or wearing away or anything like that.

Challenging and satisfying
Bought this for someone who loves physical puzzles such as the Rubick's Cube, and he loved it. Satisfyingly heavy, complex and interesting to think through. It took a while to solve, and he kept going back to it to re-solve it.

Great puzzle. Don't let dimensions fool you.
Brought as a present for my elderly father in law. Solved in a few hours! The gentleman in question does spend a lot of time on puzzles and lock picking though! The puzzle itself is quite small and light. Packaged and presented really well. An elegant item and one which is worth it to keep a mind occupied - however quickly it takes to solve!

Screw me over
Best puzzle I’ve done so far took some time as a newbie and really enjoyed the detail and minuscule movement needed to beat it. This is where you should start if you like a challenge. Anyone suggest anything on a similar level worth buying? Pros - weighty, good build quality, the sound throws you, great balance, thick wine solid Cons - smells a bit, everyone wants a go when you’re struggling, addictive structure you’re day around beating this.

Anspruchsvoll
Kniffliger Ratespaß, Geduld und viel Köpfchen gefragt, erfordert Geschick. Definitiv nichts für Anfänger. Hat seinen Reiz auch nicht verloren als es gelöst wurde. Natürlich ganz klare Kaufempfehlung, hat Suchtpotential, macht Freude.

Fabuloso y bien acabado
Para todo apasionado de los puzzles y rompecabezas, la dificultad supone un reto. Éste no es un puzzle fácil de resolver, si bien te harás con él en cuanto empieces a conocerlo. Es enrevesado y divertido. Y, lo mejor, está bien acabado y pesa. Lo que esperaba.

Joli objet. Difficulté surévaluée.
Joli objet. Ne semble pas, au toucher, aussi massif que la plupart des autres casses têtes de la gamme. Au premier abord, aucun degré de liberté n'est visible mais la solution se trouve très vite. Ne mérite pas le niveau de difficulté 6.

Belle fabrication
J'ai découvert tout récemment la série Huzzle. Et celui ci est mon tout premier. Il n'est pas difficile en fait. Mais la manipulation n'est pas si aisé; si comme moi, vous avez des gros doigts boudinnés :) Du coup, on réfléchit davantage avant de faire tourner les morceaux de pizza dans le casse-tête. Bon il est tellement bien, je m'en recommande deux autres...allez hop !
