I'm relatively new to cubing and this was a good upgrade from my previous $13 cube. It is quite a change, but a change for the better, it's fast and requires you to be more accurate, my last cube was rather lenient with poor turning. It is definitely fast and requires less effort from my previous cube, and the adjustments make personalisation more achievable.
Overall I'd say it is a great cube, although there are some things here and there that could, in my opinion, be tweaked or added, they are very minimal and can barely notice. But then again my cubing experience is limited, so this review is more from a beginner's stand point.
