I enjoy this cube over other floppy cubes because of the extra challenge. If you scramble it with only double turns, then solve it with only double turns, that is one way to use it. The challenge I appreciate is the colored "center edge" pieces. When you do single turns, unlike a normal super floppy, these get noticeably scrambled. You then have to figure out how to solve these in addition to the outside pieces. These don't get scrambled (to my knowledge) when you scramble with double turns only, hence the title. My only complaint is that this cube is a bit stiff when turning (corners and edges rubbing against each other). If you are new to cubing and want an easy floppy cube to solve, this might not be the puzzle for you. That being said, all the algorithms are still purely intuitive.
