I like this cube because of its larger size as I have quite large hands and have found smaller cubes more difficult to solve in the past because of this.
The only problem I have with this cube is the noise it makes- it is the loudest cube I have ever solved (even after adjusting its tension) and sounds like I am shaking some kind of rattle when I am solving it, but once I got used to that I managed to solve it just as quickly as any other 3x3 cube I have solved in the past (and with less effort because of its larger size).
