Fun to Play - Cognitive Exercise Too!
I spent the early years of my professional life as a psychologist. As such, I gave hundreds of intelligence tests to children and adults. These cubes are nearly identical (sans the color) as the intelligence test blocks. The block challenges can be obtained via your smartphone or a downloaded PDF file. The block design challenges are excellent cognitive building exercises for children and adults. I highly recommend these blocks for fun and staying mentally sharp.

A must-have for children
I ordered this for my granddaughter. I had a set like this when I was young that was made of painted wood. I absolutely loved it and spent hours making different pictures and patterns. When I first took it out of the box, I confess that I spent a bit of time playing with this one. This is not only a fun toy, but it is great at fostering both creativity and thinking skills. The toy comes with a link to get patterns to copy, and that is great. Free play with it is also great to let the child discover her own patterns and pictures. I did count down one star because of a production glitch. This set is (I'm nearly sure) 3D printed. While most of the blocks are fine, a couple of them are not lined up well where the blue and white triangles meet. These are off in some places by a couple of millimeters. I do believe this set is very durable and my grandchildren love it. I would definitely order this again and I highly recommend it.

I liked the size of the cubes and ease of handling. I used them with my 9 year old granddaughter to teach her spatial awareness.

Wir hatten bereits die Natural Edition dieser IQ-Testwürfel und haben uns jetzt zusätzlich die blaue Variante geholt – einfach, um zu zweit gleichzeitig üben zu können und dabei ein bisschen Wettbewerb reinzubringen. Unser Sohn findet die blauen sogar „cooler“ und ich muss sagen, dass sie auf dem Tisch etwas kontrastreicher wirken – gerade bei schwächerem Licht. Wie auch bei der Natur-Edition ist die Qualität top: 9 sauber gedruckte Würfel, ca. 2,5 cm groß, leicht und trotzdem stabil. Die Kanten sind angenehm abgerundet, nichts scharf oder verzogen. Die Würfel stehen gut und lassen sich problemlos stapeln und drehen, ohne ständig wegzukippen. Ein tolles Set – ob blau oder natur – für alle, die IQ-Testmuster üben wollen oder einfach eine hochwertige Konzentrations- und Denkspiel-Alternative suchen.

PrfcNL Test Cubes (Blue & White) – 9 Kohs Cubes are basically hard hollow triangles glued together to form squares. The cubes are simple cube but to be honest for the price they are the cheapest plastic out there with sharp edges so I am a little disappointed. It would not go to the website since google was saying it is not secure and on my laptop it needed something else to download to run it. Eventually I downloaded a pdf. They are way overpriced for what it is but it is handy in testing children and older adults and working dexterity as well.

I'm very disappointed with the quality of this product. It is 3D printed. It doesn't have a smooth finish, it has sharp edges and points. The size is precisely one inch, but as it turns out, one inch is smaller than the real thing they use at the real tests.
