This is the perfect toy for your puzzle minded child. My son loves rubik's cubes and anything he has to use his mind to solve. It took him a little bit to solve it, but he finally did it. It provides lots of entertainment. I am sure he will continue to solve it over and over. Great addition to his rubik's collection.
I am a huge fan of the Rubik's Cube and thought this puzzle might be a fun challenge. Once I got it, I found the movement of the gears very satisfying and the puzzle to be quite complicated, but solvable. Believe me, you won't be disappointed.
I love this puzzle! The gears feel so cool and never get stuck. I'm not sure about the intermediate rating -- it's pretty hard. I would definitely buy another for the geeky friends on my shopping list this holiday.
