First note, it REALLY takes some nreaking in at first. I went from an RS3 to this one, and not only was it fighting my sloppy corner cutting, it was locking up a lot more than I would have liked. I started doubting the cube but decided to spend a weekend breaking it in without lubricant. Let me tell you, patience is key while breaking in this cube. Meanwhile, I feel like it still rewarded precise movements which I believe may have "corrected" bad posture in my finger tricks. This cube, like a leather boot, takes a lot of effort and patience but it really feels like i have adjusted into it. Now when the cube is cleaned and lubricated, it feels like butter. I've gotten so used to the lighter settings that I couldn't cube any other way; the movement feels so liquid and light and the momentum characteristics really reward fast and precise movements that seem to just pop nicely into place with little effort. Highly recommended.
