I am going to modify my V-Cube 5 and 6 and I heard they have to be broken in first.
How can I tell when it is broken in? I have been solving them a lot of times, but they still feel the same. How long does it usually take for the V-Cubes to be broken in from the day I got them?
Oh, and also I am going to be doing a full mod for the V-Cube 5 and 6, using memyselfandpi's tutorial.
