I already had the Amazon version of this. It’s adequate as a puzzle. The Craighill Tetra is in another category. It is bigger, heavier, smooth and polished stainless, beautifully engineered, a pleasure to just look at, and to hold in your hand, It is a work of art, whether assembled or disassembled, even in various stages of assembly. And, as a classic work of art, it is reasonably priced!

Ein geniales Knobelspiel

Well made. It took me about half an hour to get apart and then about 10 minutes to get it back together.

Tetra Puzzle is my first Craighill puzzle and I love it! I am an amateur puzzler and solved so many puzzles since I was little. I have never encountered a puzzle like Tetra Puzzle. When you assemble three base parts and put the fourth one on top, gravity will take care to complete the puzzle. I get settled satisfaction. I want to play with it at least once a day.

And I like the name, too. Tetra - four parts -, is better than a pyramid puzzle.

This Tetra Puzzle is Absolutely Amazing. I love it.

Just by picking it up, with how heavy it is tells you that it's made very well. The craftsmanship is superb. What an Awesome Company. I highly recommend everyone to check out Craighill. I want to add the Venn Puzzle to my collection as well.
