At first I didn't like it at all... it gave me a two-day headache. But after breaking it in and adjusting the spring tension (5-days later) it started to live up to all the hype. After lube with weight 5 in the [teeny-tiny] core and weight 3 on the pieces, it feels like a completely different cube. I really like the colors and the way the magnets keep the square shape. I didn't find any difference with the ball bearings so I yanked them out, thinking that they could only cause a problem if they were actually in the cube. The weight of this cube is very light and easily compares to my GAN 356 Air S, but that's where the simlarites end because it has it's own unique feel, which also takes some time to get used to.
The hardware includes four washers in each center piece (one pair on each end of the spring), for a total 24 washers for the entire cube. I guess this is Yuxin's attempt to have a core that does not need lubrication. But since I like to mess with stuff like that anyway, their strategy went unnoticed. I arranged the two washers such that the smooth sides faced each other with lube inside (like two lube sandwiches) on each end of the spring.

But the real reason I give 5-Stars is because I can't edit my review at a later date, and I know I'm liking this cube more and more as time goes by, and the CFOP Chart is just an added bonus and very informative for any level of player... thanks Yuxin!
