Right out of the box, it was my main over my well worn GAN 356S v2. The turning was very light, and the way the tensions were set up, it almost feels magnetic, as long as you turn slowly. I loosened it up a little and it felt even better. The cube is quite stable and performs very well. I prefer a much brighter orange, yellow, and green, all three of which could get mixed up with their counter parts in poor lighting, but the shades are usable. I haven't tried other GES nuts, but the clear ones that came with the cube feel fine.
Still haven't set it up, and probably wont, since it feels really nice dry. If I do, it would only involve a small amount of heavy lube on core and pieces.
