Fun cube, larger than expected though. The "3x3" aspect" only really exists to mix up the balls inside. If the puzzle is not aligned, the balls are very hard to turn. Putting it on the table after a turn may help if the balls won't move.

It's big! I didn't expect that. It's a good cube. It turns well when beans are aligned. Beans turn well too with just one finger. It's very durable. It's stickerless.
