Very nice, it is relatively well made, of course it has not fallen down for me, but it is comfortable and durable in the hand, not fake. No matter how much time passes, you pick it up again to solve it! It also works as an anxiety reliever!

It's not bad, just very fragile. I bought it twice because the first one fell from the child's hands in an outdoor area and the balls got lost. If it breaks in a space where someone can find all the pieces, it can be reassembled again.

Interesting game but every time it falls down, it breaks apart and we have to search for the balls! We have to put it back together and start over again!

It lasted 3 days. As soon as it fell from the child's hands to the floor, we were picking up the balls. Of course, it couldn't stick back together.
Of course, we threw it away. It's a shame because visually it looks well-made.

Good construction quality. It requires some force to move the ball to the next position. Difficult for a child aged 5+ who is not familiar with similar games (e.g. Rubik's Cube). It keeps the interest.
