Magic Cube Rainbow Ball

Pros: Good quality, easy to solve puzzle with nice bright colors. Seems solid, my son played with it a few times without breaking it or damaging the inner sponge. All colors are easy to recognize to put all the balls back to their places.

Cons: This puzzle doesn't use any internal mechanism. A simple sponge is used to act as a spring to push back the color balls into their respective color holes. Perhaps the sponge won't last for years, but for now, after about 1 year it's still OK.

Other: To solve the puzzle, place the good color-ball in the matching color hole.

Pros: this is an excellent little puzzle, in line with rubik's cube type puzzles but a little easier and more intuitive than a rubik's cube its very sturdy and solidly built, i never felt i had to be careful when handling it or that it was fragile in any way which was great

Cons: there aren't any real cons that i can think of, it can get boring if you want to play with it all the time because it gets really easy to solve

Other: definitely recommend if you're looking for a brain teaser puzzle ball
