PrfcNL IQ Test Cubes (Red and White) – 9 Kohs Cubes, Practice for Block Design Test, WPPSI, WAIS IV and WISC V Tests, Montessori Educational Blocks to Improve Concentration, Coordination and Memory

As expected.

I ordered this for my 11 year old daughter to play while we are traveling. I didn't download the pdf yet, I just had her use the app with it. It's fun and pretty self explanatory. She likes racing the clock to see how fast she can solve the puzzle. I do wish it would keep your best record, but it doesn't seem to. I like how it's exercising her brain, and she just sees it as a fun puzzle. Great for kids and adults!

These make a good practice set but aren’t smooth and have the same weight as the IQ tests if that’s what you are buying them for

Needed blocks in 2 days. They got the job done, but are not durable. Very light and not as easy to handle as the real ones which have more weight to them. After 8 months, 2 of them broke. They are glued together and if used by children, the red and white halves can be easily pulled apart. You get what you pay for.

El producto llegó incompleto y abierto. El material es de mala calidad.

Bad Quality Not recomended

Not much to say beyond that it came incomplete. It was missing a cube and thus utterly useless. Too bad, the idea and app that come with it are awesome. Unfortunately it was all undermined by poor execution.
