It's a really good cube, but the thing is it sucks without lube. I have one which i used for 2 weeks, then it started popping like crazy. I added some maru lube, and I have to say its a lot better than the new one I got (with my shengshou wind) I would say go for the shengshou wind instead, its not that much more expensive. If lubed and tensioned well, the shengshou wind can cut 45 degrees and reverse corner cut 3/4 of a cubie. I actually like it a lot more than my guhong v1.
