I recently bought this and I must say, for being an old school cube, it is better than most cubes. It has supreme corner cutting being one of the ifrst 2 by 2s to have the cuts in the peices. This adds up to very good corner cutting on looser tensions, but major pops. The only downside to this cube is that out of the box it is quite bumpy, not because of the hard plastic, but because of the mechanhism. Although it isnt super hard to set up, I find it hard to have a tight cube that doesnt pop when I have other loose cubes that don't pop.
Although it does pop majorly, it does do well on tighter tensions. And I also might add that it is really easy to lube and tension. I poped out a side, put cube slick lube in all the nooks and crannies, and added 4 drops of lubicle silk and it performs like a dream. The only reason I however am not giving it 5 stars is because of the popping aspect. If dayan can make perhaps a bigger corner peice stem thing and make the edge peices have an anti popping mechanism, I think it would be the perfect cube for cubes that like controlable and BUTTERY smooth cubes. I highly recomend this cube if you A Can deal w/ tight tensinos B Are sub at least 10, C Know's how to poroperly setup cubes, or D Don't really care abouyt the fact that out of the box it neither fast or smooth. If any of these apply to you, I would highly recomend even w/ it's steap price tag
