It doesn't get better than this; great inners, even better outers, perfect magnets, and $22. If you are looking for a 6x6, look no further.

As the title states, this 6x6 is the best on the market by far. Out of the box, it's quite loose and greasy, but after tightening each side about 180 degrees and breaking in with ~50 solves, this cube has become an amazing 6x6 and makes 6x6 enjoyable to practice!

I don't do 6x6, but from what I can tell, this is a very good cube. However, I don't know how to set it up, and get even tensions, but I accidentally popped it, as it comes on loose tensions.
