Best cube for practicing edge algorithms!
Title pretty much says it all. If you can solve a 3x3, you can solve this cube, as you simply solve the edge pieces as you would for a 3x3. If you struggle with those algorithms, this cube could prove to be invaluable. It doesn't turn very well at first, and there is almost no corner-cutting to be had, perhaps making it slightly less than ideal for a speed solver, but it is a great and unique practice tool! Definitely a worthy purchase!
