Good light cube that is quiet and smooth. Out of the box, the magnets are too strong. I have edge magnets at the first dot (one above the -), and all core tensions at 3. I think the cube is very smooth and forgiving, if you have good turning. My main problem is that the center caps are a total pain to try to get off and leave my fingers feeling painful and dented. I set it up with Comet, and it's nice and quiet. Overall, a lovely cube with nice color shades. I think the yellow could be darker or more orangey, as it's hard to cube in yellowish light (like next to a lamp) but it's not that big of a problem. I like the red and blues.
